The 13-inch M3 model suits students and mobile professionals needing under 1.24 kg weight and 18 hours of video playback, with its 52.6 Wh battery lasting longer than most Windows ultrabooks. The 15-inch M4 is for creatives editing 4K video or running Docker containers across 24 GB RAM, benefiting from its 66.5 Wh battery (21 hours playback) and larger 340.4 mm screen for multitasking. In UAE at AED 5899 vs AED 7399, the M3 is better because it saves AED 1500 with 90% of the performance; in India at ₹144900 vs ₹184900, the M3 wins on value because ₹40000 saved offsets the smaller screen for most workflows.
