I have the 14 inch M3 Pro currently.. I have had 13inch 2010 MBP, then M1 Air 13inch(too small), then 13inch M2 Air then 15 inch M2 Air before upgrading to 14 inch pro.
I am missing now the larger display of M2 Air 15, as I find 14 inch bit too small. Next time I am getting a bigger MacBook surely, 16 inch Pro or 15 inches Air at least.
my MacBook barely gets out of the house. The larger screen MacBook have better battery life, larger immersive screen, larger trackpad for effortless scroll, larger wrist rest area for comfort. I think if 15inches Air gets some mini led it would be dope, otherwise 16 inches would be okay but it comes with a heft surely.
