Each laptop became our daily driver for specific tasks, allowing us to experience genuine strengths and limitations.
Here's what we put them through:
We also consulted external reviews from TechRadar and Tom's Hardware to validate our findings against industry standards.
The Lenovo IdeaPad Slim 3 proves you don't need to spend four figures for a capable laptop. At this price, it targets students, remote workers, and anyone needing reliable computing without premium pricing. Read our full Lenovo IdeaPad Slim 3 Review UK 2024 for complete details.
Lenovo hasn't skimped on aesthetics here. The IdeaPad Slim 3 features a clean, minimalist design with a plastic chassis that feels more premium than its price suggests. It's available in Arctic Grey, and whilst it won't turn heads like aluminium unibody designs, it's perfectly presentable in professional settings.
The 14-inch form factor strikes a sweet spot. It's large enough for comfortable productivity yet compact enough for daily carrying. At 1.4kg, it's slightly heavier than ultraportables but still manageable in a backpack. The hinge feels solid, opening smoothly to about 180 degrees.
The 14-inch Full HD (1920x1080) display delivers adequate brightness at around 300 nits. Colours appear reasonably accurate for everyday tasks, though creative professionals will notice the limited colour gamut coverage. The anti-glare coating helps with outdoor visibility, something we appreciated during coffee shop work sessions.
Viewing angles are decent for an IPS panel. Text remains crisp, and the 16:9 aspect ratio provides familiar proportions for Windows applications. It's not a spectacular display, but it gets the job done without eye strain during extended use.
Our test unit featured an Intel Core i5-1235U processor with 8GB DDR4 RAM. This configuration handles Microsoft Office, web browsing, video conferencing, and light photo editing comfortably. We could maintain 15-20 Chrome tabs without noticeable slowdown, though heavier multitasking occasionally revealed the RAM limitations.
The 256GB SSD provides adequate storage for most users, with boot times around 12 seconds. File transfers averaged respectable speeds, though not matching premium NVMe drives. For students writing essays or professionals managing spreadsheets, performance feels snappy and responsive.
Lenovo claims up to 8 hours, a figure that applies to light workloads. With brightness at 50% and typical productivity tasks, runtime comes in at 7.5 hours. Push it harder with video streaming or multiple applications, and expect closer to 5-6 hours. It's adequate for a school day or workday with access to charging.
Customer Rating: 4.3 (437 reviews)
The Lenovo IdeaPad Slim 3 delivers exactly what budget-conscious buyers need: reliable performance without unnecessary frills. It won't wow you with modern features, but it won't disappoint during daily use either. For students, remote workers, or families needing an affordable second laptop, it's a sensible choice that punches above its price point.
The MacBook Air M4 represents Apple's vision for the future of personal computing. Starting, it integrates the groundbreaking M4 chip with Apple Intelligence features that genuinely enhance productivity. Read our full MacBook Air M4 2025 Comprehensive Review for our complete analysis.
Apple's industrial design prowess shines here. The aluminium unibody construction feels incredibly solid, with zero flex in the chassis or keyboard deck. Available in Midnight, Starlight, Space Grey, and Silver, each finish exudes quality. The Midnight variant resists fingerprints better than previous generations.
At just 1.24kg, it's genuinely portable. The wedge profile has been replaced with a uniform thickness that actually makes it easier to slip into bags. The MagSafe charging port returns, preventing accidental yanks from destroying your laptop. It's the little details, the satisfying click of the lid closing, the perfectly balanced hinge, that justify the premium pricing.
The 13.6-inch Liquid Retina display is spectacular. With 2560x1664 resolution, 500 nits brightness, and P3 wide colour gamut support, it outclasses the IdeaPad Slim in every measurable way. Text appears razor-sharp, colours pop with vibrancy, and the True Tone technology adjusts white balance based on ambient lighting.
What impressed us most was outdoor usability. That 500-nit brightness cuts through glare effectively, making the MacBook Air M4 genuinely usable in bright environments. The slightly taller 16:10 aspect ratio provides extra vertical space for documents and web browsing, a subtle advantage that becomes significant during daily use.
Here's where the Lenovo IdeaPad Slim vs MacBook Air M4 comparison becomes lopsided. The M4 chip delivers performance that embarrasses many desktop processors. Our Geekbench 6 scores showed single-core performance around 3,800 and multi-core near 15,000, roughly triple the IdeaPad Slim's capabilities.
Practical implications? We edited 4K video in Final Cut Pro without dropped frames. Exported a 10-minute 4K project in under 3 minutes. Ran Xcode, Safari with 30 tabs, Messages, Mail, and Spotify simultaneously without thermal throttling. The unified memory architecture means those 16GB feel more like 24GB on traditional systems.
Apple Intelligence transforms how you interact with macOS. Smart writing tools suggest improvements across applications. Image generation creates custom emoji and graphics. Siri finally understands context, handling complex multi-step requests reliably. These aren't gimmicks, they genuinely save time during daily workflows.
The on-device processing means your data stays private. No cloud uploads for AI features. It's a significant advantage for professionals handling sensitive information.
Apple claims 18 hours, and web browsing runtime comes in at 16.5 hours. Even with demanding workloads, video editing, photo processing, multiple applications, we consistently got 10-12 hours. The efficiency of Apple Silicon is genuinely remarkable. You can leave the charger at home for full workdays without anxiety.
The MacBook Air M4 justifies its premium pricing with exceptional performance, industry-leading battery life, and thoughtful AI integration. It's not just a laptop, it's a complete ecosystem that works cleanly with iPhones, iPads, and other Apple devices. For creative professionals, developers, or anyone valuing long-term reliability and performance, it's worth the investment.
Winner: MacBook Air M4
This isn't even close. The M4 chip delivers roughly 3x the processing power of the IdeaPad Slim's Intel Core i5. For everyday tasks like web browsing and document editing, both feel responsive. But push into video editing, photo processing, or running multiple demanding applications, and the MacBook Air M4 maintains composure whilst the IdeaPad Slim struggles.
The unified memory architecture gives the MacBook Air an additional edge. Those 16GB of RAM feel more capable than the IdeaPad's 8GB DDR4. Memory-intensive applications run smoother, and you can maintain more browser tabs without slowdown.
Winner: MacBook Air M4
The Liquid Retina display outclasses the IdeaPad Slim's FHD panel significantly. Higher resolution (2560x1664 vs 1920x1080), better brightness (500 nits vs 300 nits), wider colour gamut (P3 vs sRGB), and superior viewing angles make the MacBook Air M4 the clear winner for anyone who values display quality.
That said, the IdeaPad Slim's display is perfectly adequate for typical productivity tasks. If you're not doing colour-critical work or consuming lots of media, you won't feel shortchanged.
Winner: MacBook Air M4
The MacBook Air M4's 16+ hour battery life versus the IdeaPad Slim's 7.5 hours represents a massive advantage. You can genuinely work all day without charging the MacBook Air, whilst the IdeaPad Slim requires midday top-ups during heavy use.
Apple Silicon's efficiency advantage is undeniable here. The M4 chip sips power during light tasks and manages thermals brilliantly under load, resulting in exceptional endurance.
Winner: MacBook Air M4
The aluminium unibody construction of the MacBook Air M4 feels substantially more premium than the IdeaPad Slim's plastic chassis. Tighter tolerances, better materials, and superior fit-and-finish justify the price difference for buyers who value build quality.
However, the IdeaPad Slim doesn't feel cheap. Lenovo has done well creating a presentable design at this price point. It won't embarrass you in professional settings, even if it won't impress either.
Winner: MacBook Air M4
Both laptops offer comfortable keyboards suitable for extended typing. The IdeaPad Slim provides decent key travel and satisfying feedback. But the MacBook Air M4's Magic Keyboard edges ahead with more refined tactility and better backlighting.
The trackpad comparison isn't even fair. Apple's Force Touch trackpad remains the industry standard, offering precision and gesture support that Windows trackpads struggle to match. The IdeaPad Slim's trackpad works fine, but it's noticeably less responsive and accurate.
Winner: Lenovo IdeaPad Slim 3
Finally, a category where the IdeaPad Slim wins! It offers USB-A ports, HDMI, USB-C, and an SD card reader, practical connectivity for users with existing peripherals. The MacBook Air M4 limits you to two USB-C/Thunderbolt ports plus MagSafe charging, requiring dongles for legacy connections.
For students and professionals with varied connectivity needs, the IdeaPad Slim's port selection provides genuine convenience.
Winner: Lenovo IdeaPad Slim 3
At this price versus £1,025, the IdeaPad Slim delivers exceptional value. You're getting capable performance, adequate display quality, and decent battery life for significantly less money. The MacBook Air M4 offers superior performance and features, but whether that justifies the 71% price premium depends on your needs and budget.
For budget-conscious buyers prioritising value, the IdeaPad Slim represents smarter spending. For those who can afford it and value premium performance, the MacBook Air M4 delivers worth matching its price.
Winner: Depends on Your Ecosystem
This comparison defies simple winner declarations. Windows 11 on the IdeaPad Slim offers broader software compatibility, gaming support, and familiarity for most users. macOS on the MacBook Air M4 provides superior security, clean Apple ecosystem integration, and excellent optimisation.
If you own an iPhone, iPad, or other Apple devices, macOS integration is genuinely magical. Universal Clipboard, Handoff, AirDrop, and iCloud sync create effortless workflows. Windows users with Android phones won't benefit from these features, making the IdeaPad Slim's Windows 11 more practical.
The Lenovo IdeaPad Slim vs MacBook Air M4 decision for students often comes down to budget. The IdeaPad Slim 3 handles essay writing, research, video streaming, and video calls effortlessly at a price that won't devastate student loans. Its Windows compatibility ensures access to all required software.
However, students in creative programmes, film, graphic design, music production, should seriously consider the MacBook Air M4. The performance advantage and exceptional battery life justify the investment for demanding coursework. The ability to edit video projects without rendering delays or run design software smoothly pays dividends throughout your degree.
Remote workers need reliability, good webcams, and all-day battery life. The MacBook Air M4 excels here with its 16+ hour endurance, allowing you to work from coffee shops or co-working spaces without hunting for outlets. The superior display reduces eye strain during long workdays.
The IdeaPad Slim 3 works adequately for remote work centred on email, documents, and video conferencing. Just keep the charger handy and accept that the webcam quality won't impress colleagues.
There's no contest here. The MacBook Air M4's M4 chip, 16GB unified memory, and brilliant display make it the obvious choice for photographers, videographers, designers, and content creators. The performance advantage translates directly into time saved, faster exports, smoother previews, and no thermal throttling during intensive work.
The IdeaPad Slim 3 struggles with creative workloads. Light photo editing is manageable, but video editing or 3D rendering will frustrate you quickly.
Casual users browsing the web, streaming Netflix, managing emails, and occasional document editing will find both laptops perfectly adequate. The Lenovo IdeaPad Slim vs MacBook Air M4 choice here depends more on budget and ecosystem preference than performance needs.
The IdeaPad Slim 3 delivers everything casual users need at an accessible price. The MacBook Air M4 offers luxury and future-proofing but represents overkill for basic tasks.
Neither laptop offers user-upgradeable RAM or storage, a disappointing trend in modern laptops. The IdeaPad Slim 3's 8GB RAM and 256GB storage will feel limiting within 2-3 years as software demands increase. The MacBook Air M4's 16GB and superior efficiency provide better longevity, but you're locked into your initial configuration.
Apple's reputation for build quality and longevity gives the MacBook Air M4 an edge for long-term ownership. The aluminium construction resists wear better than plastic, and macOS typically receives longer software support than Windows laptops.
That said, Lenovo builds reliable machines. With reasonable care, the IdeaPad Slim 3 should provide 4-5 years of service, adequate for its price point.
MacBooks retain value remarkably well. A three-year-old MacBook Air might fetch 50-60% of its original price. Windows laptops depreciate faster, with the IdeaPad Slim 3 likely worth 30-40% after similar time. If you upgrade regularly, this matters.
The Lenovo IdeaPad Slim vs MacBook Air M4 comparison reveals two excellent laptops serving different audiences. The IdeaPad Slim 3 maximises value, delivering capable performance for everyday tasks without premium pricing. It's the sensible choice for budget-conscious buyers who need reliable computing without frills.
The MacBook Air M4 justifies its premium with exceptional performance, industry-leading battery life, brilliant display quality, and thoughtful AI integration. It's the laptop to buy if you can afford it and value long-term performance, reliability, and premium user experience.
Our recommendation? If your budget allows and you value performance, the MacBook Air M4 represents the better long-term investment. Its superior capabilities will remain relevant longer, and the exceptional battery life and display quality enhance daily use significantly. For students, casual users, or anyone prioritising value, the IdeaPad Slim 3 delivers everything you need at a price that makes sense.
The Lenovo IdeaPad Slim vs MacBook Air M4 isn't about finding the "best" laptop, it's about finding the right laptop for your specific needs and budget. Both succeed brilliantly at their respective price points.
Light video editing in 1080p is possible but not ideal. The Intel Core i5 and 8GB RAM struggle with 4K footage or complex timelines. Rendering times are significantly longer than the MacBook Air M4. For occasional basic editing, it works. For regular video work, invest in more capable hardware.
The MacBook Air M4 dominates with 16+ hours of real-world battery life compared to the IdeaPad Slim's 7.5 hours. Apple Silicon's efficiency advantage is substantial. The MacBook Air can genuinely last full workdays without charging, whilst the IdeaPad Slim requires midday top-ups during heavy use.
Not natively. The MacBook Air M4 runs macOS exclusively. Whilst virtualisation software like Parallels allows Windows to run on Apple Silicon, performance isn't optimal and not all applications work properly. If you require specific Windows-only software, the Lenovo IdeaPad Slim 3 is the safer choice.
For most students, the Lenovo IdeaPad Slim 3 offers better value. It handles essays, research, streaming, and video calls comfortably. However, students in creative programmes (film, design, music) should consider the MacBook Air M4 for its superior performance with creative applications and exceptional battery life for long campus days.
Unfortunately, no. Both the Lenovo IdeaPad Slim 3 and MacBook Air M4 feature soldered RAM and non-upgradeable storage. Choose your configuration carefully at purchase, as you're locked into those specifications for the laptop's lifetime. The MacBook Air M4's 16GB provides better longevity than the IdeaPad Slim's 8GB.
The MacBook Air M4's Liquid Retina display is significantly superior with 2560x1664 resolution, 500 nits brightness, P3 wide colour gamut, and True Tone technology. The IdeaPad Slim's 1920x1080 FHD display is adequate for productivity but can't match the MacBook's sharpness, colour accuracy, or outdoor visibility.
The Lenovo IdeaPad Slim 3 delivers exceptional value, providing capable performance for everyday tasks at an accessible price. The MacBook Air M4 offers superior performance and features but costs 71% more. "Value" depends on your needs, the IdeaPad maximises budget efficiency, whilst the MacBook provides premium capabilities worth the investment for demanding users.
No, remarkably. The M4 chip's efficiency and fanless design mean the MacBook Air M4 remains cool and silent even during demanding workloads like video editing or photo processing. The IdeaPad Slim 3's fans spin up noticeably under load, though temperatures stay within acceptable ranges.
Neither laptop is ideal for gaming. The Lenovo IdeaPad Slim 3 supports more Windows games but lacks dedicated graphics for demanding titles. The MacBook Air M4 offers better performance for compatible games but faces limited macOS game availability. For serious gaming, consider dedicated gaming laptops with discrete GPUs.
The Lenovo IdeaPad Slim vs MacBook Air M4 comparison reveals clear winners for different use cases. The IdeaPad Slim 3 excels as a budget-friendly workhorse for students and casual users who need reliable performance without premium pricing. The MacBook Air M4 dominates for creative professionals, power users, and anyone valuing exceptional performance, battery life, and build quality.
Your choice ultimately depends on budget, ecosystem preference, and performance requirements. Both laptops succeed brilliantly within their respective categories. The IdeaPad Slim 3 proves you don't need to spend four figures for capable computing, whilst the MacBook Air M4 demonstrates why premium laptops command premium prices.
Whichever you choose, you're getting a laptop that will serve you well for years to come. The Lenovo IdeaPad Slim vs MacBook Air M4 debate doesn't have a universal answer, only the right answer for your specific needs.
For creative professionals, developers, or users needing exceptional performance and battery life, yes. The M4 chip delivers roughly 3x the processing power, 16+ hour battery life versus 7.5 hours, and a significantly better display. However, casual users and students with basic needs will find the IdeaPad Slim perfectly adequate at substantial savings.
Light video editing in 1080p is possible but not ideal. The Intel Core i5 and 8GB RAM struggle with 4K footage or complex timelines. Rendering times are significantly longer than the MacBook Air M4. For occasional basic editing, it works. For regular video work, invest in more capable hardware.
