I got my 16 GB Macbook Air for $1000 at Microcenter. For development purposes it's the same as a Pro, except it doesn't have a fan (and has never throttled) and doesn't have a touch bar (which is great)
The MBA is an insane value with the advent of the M1, a complete turnaround from the old days.
Also it has a trick up it's sleeve when it comes to this:
> the complete lack of repairability. As a reminder, your Mac's battery will die at some point, and your Mac will become useless.
First off, Apple will replace the battery in a MBA for $129 (vs $200 for the MBP), so a little alarmist...
But more importantly the new Air uses stretch-release adhesive (think command strips) and doesn't require removing the logic board for battery replacements. The MBP didn't inherent this improvement.
It's no Framework but it makes it the value proposition that much sweeter...
