The iPad Pro proves that weight and battery life is no excuse here for the lack of state-of-the-art display tech in the MacBook Air. And as for cost — the base 14” MacBook Pro M4 (at $1600) isn’t significantly more expensive than the 15” MacBook Air M4 configured with same CPU/RAM/SSD (at $1400).
It’s really quite a shame that the iPad Pro hardware is in many way a better MacBook Air than the MacBook Air, crippled primarily by iOS rather than hardware.
