MacBook Air M4 vs Windows Ultrabooks: Best Laptops of 2026

The Apple MacBook Air M4 features a 10-core CPU that excels in efficiency, with up to 18 hours of battery life, while the Intel Core Ultra 7 256V in the Dell XPS 13 boasts a remarkable battery life of up to 26 hours on the FHD+ configuration. The Snapdragon X in the Microsoft Surface Laptop 7 delivers an impressive 20 hours of battery life, but struggles with app compatibility compared to its Intel and Apple counterparts. In terms of raw performance, the M4 chip offers significant advantages in both CPU and GPU tasks, particularly for creative workloads. Overall, if you're looking for the best performance per watt, the Intel-based Dell XPS 13 edges out slightly due to its extended battery life.

The MacBook Air's Liquid Retina display, available in 13.6 and 15.3 inches, boasts a resolution of 2560 x 1664 and 2880 x 1864, respectively, both with a brightness of 500 nits. In comparison, the Dell XPS 13 offers a stunning InfinityEdge display with up to 2880 x 1800 resolution and optional 3.5K OLED, providing vibrant colors and deep contrasts. The Surface Laptop 7's 120Hz PixelSense display stands out with a resolution of 2304 x 1536 and a brightness of 600 nits, making it excellent for multimedia consumption. However, the MacBook Air's 18-hour battery life remains competitive against the XPS 13's claim of 26 hours, making it a strong contender for users who prioritize both visuals and longevity.

The MacBook Air M4 starts at $999 for the 13-inch model and $1,199 for the 15-inch version, offering robust performance at a competitive price. The Dell XPS 13 begins around $1,299, which is higher than the base MacBook Air, but offers excellent build quality and features. The Surface Laptop 7 is priced around $1,099, making it a mid-range option that provides solid performance and a high-quality display. Ultimately, for those on a budget, the MacBook Air provides the best value, while the Dell XPS justifies its higher price with premium features and battery life.

The MacBook Air is equipped with two Thunderbolt 4 ports and a MagSafe 3 connector, which may limit connectivity options for some users. In contrast, the Dell XPS 13 also offers two Thunderbolt 4 ports but lacks additional ports, necessitating adapters for external connections. The Surface Laptop 7 provides a more versatile port selection with two USB-C ports, one USB-A port, and a 3.5mm headphone jack, making it easier to connect various peripherals. Repairability is a concern for all three models, especially the MacBook Air and XPS, which are challenging to service due to their tightly integrated designs.

For students, the MacBook Air M4 offers a lightweight design and long battery life, making it ideal for on-the-go use. Creators will appreciate the processing power of the M4 chip, especially with the enhanced graphics capabilities. Business users may find the Dell XPS 13's premium build and extended battery life more appealing for professional environments. The Surface Laptop 7 shines in casual use, thanks to its excellent display and portability, but may not meet the demands of more intensive tasks due to its ARM architecture. Each laptop has its strengths, catering to different user needs.
