Apple MacBook Air 15" M4 vs Samsung Galaxy Book4 Pro
The Verdict
Apple's MacBook Air M4 delivers exceptional portability at an aggressive price point, weighing just 3.3 lbs with a 15.3-inch display and claiming 18 hours of battery life. Samsung's Galaxy Book4 Pro counters with a larger 16-inch Dynamic AMOLED 120Hz display, superior port selection (USB-A, SD card, HDMI), and double the base storage at 512GB. Performance-wise, Intel's Core Ultra 7 155H edges out Apple's M4 in multithreaded workloads, though M4 excels in efficiency and single-threaded tasks. Battery reality favors Apple by a comfortable margin,18 hours versus 15 hours mixed use. Windows 11 offers broader software compatibility, while macOS remains more streamlined. For creative professionals needing larger screens and legacy ports, the Galaxy Book4 Pro justifies its $150 premium. However, the MacBook Air's superior battery endurance, lighter chassis, and price advantage make it the more versatile choice for general users. Recommendation: Choose MacBook Air M4 for portability and value; select Galaxy Book4 Pro if you need Windows, expandable storage, and a bigger display.
