I went from a M1 Air to my current M4 Pro; my observations:
- Don't want or like space black, on computers or phones.
- Don't care about cores. I can't tell any difference, whatsoever, in day-to-day usage.
- Screen is better, but not enough to matter.
- 14 vs 13 screen. Nice, but not a big deal.
- I don't buy base storage regardless of the model. Minimum 1tb.
- HDMI was already available with a multi-port splitter, which I still carry.
- Same for the SD card slot.
- Battery is fine on both.
What I do miss is the wedge shape, the lighter weight, the lack of a fan, and lack of fan grates on the sides. I kind of wish I had waited for the M4 Air, but I wanted to get my upgrades in before tariffs.
The only thing I really like is having a usb-c port on both sides.
