The MBA 13 and MBP 14 have very similar working real estate on their displays. See their default scaled resolutions for better understanding.
The MBA 15 and MBP 16 have very similar working real estate on their displays. Again, see their default scaled resolutions for better understanding.
If someone is okay with a smaller working real estate on their display, they should consider a MBA 13 or MBP 14. If they want or need MORE working real estate, they shoud consider a MBA 15 or MBP 16.
It’s a pet-peeve of mine when people look at the price of the MBA 15 and recommend that someone get the MBP 14 instead. They are very different experiences and some people won’t be happy with the smaller working space
RDM won’t really fix the problem. If you make the resolution too high things will be too hard to read on the smaller display.
The MBP are more powerful machines and some people might get value from that. But for the majority of people, the M2 is more than fast enough. And some people will find value in the bigger display and be better off with a MBA 15 or MBP 16.
All I’m saying is if your gonna recommend someone looking at the MBA 15 get the MBP 14, make sure they are okay with going back to a MBA 13 size screen.
