With all this talk of a 15″ MacBook Air I have one small concern that the screen resolution might stay the same as for the 13.6″ version at 2560×1664 or thereabouts. It doesn’t make a lot of sense but it’s not like they haven’t done it before.
It’s a long time ago and an entirely different executive team, but when Apple introduced the 14″ iBook G4 they kept the screen resolution at 1024×768, the same as the 12″ iBook and the 12″ PowerBook G4. Those who bought the 14″ iBook didn’t get any more work space than those who bought the 12″ version.
The larger iBook had a bigger screen size, bigger hard drive, a SuperDrive that burns DVDs and CDs instead of a Combo Drive that can read DVDs but only burns CDs, and 450 grams heavier, and a higher price.
Apple didn’t want to cannibalize the slightly more expensive 12″ PowerBook G4 which had almost identical specs and they certainly didn’t want the iBook to encroach on the Pro Mac space, so they couldn’t give the 14″ iBook a higher screen resolution.
There’s little chance that someone would pick the 13″ M2 MacBook Pro if Apple makes a 15″ Air available, because frankly, why would you? Even the 13″ M2 MacBook Air is a slightly better machine overall and with a slightly lower price.
Will a 15″ Air pose a threat to the 14″ Pro? Not in the slightest. The 14″ and 16″ Pro machines carry the much more powerful M2 Pro or Max chips and they also have much higher resolution screens with the XDR display. They also have more connectivity or ports. The Air lineup will not have those.
