I upgraded to the MBA M1 16gb from a 2014 MPB 15 16Gb. The battery was starting to go, it sucked a lot of power and we live full time in a RV while working so power draw was a huge factor. I didn't go MBP because it doesn't seem to be much of an upgrade over the MBA and no touchbar is a plus (even more now that it's going away). I also wanted to smaller power supply for travel. So for us, it was a game changer upgrade but if I lived in a situation where power wasn't so much of a factor, I would have waited for gen 2 of Apple silicon
