I have a 8/512 MBA because it was the best one that you didn't have to do CTO for, and I needed a new laptop ASAP (coming from an Acer Aspire E5-576 fully specced out)
I wish that the best non-CTO would have been 16/512 on the M1 like the latest M3 MBA is otherwise I would not need to upgrade.
It is a very nice laptop still, but what I do, I will be needing 16 GB very soon, which is why I am going to buy the M3 MBA in the next coming weeks. I probably would not be upgrading if you still had to CTO on the MBA.
I could buy a used M1 MBA with 16/512, but then I would not be able to get AppleCare+, and I recently replaced the battery on this 8/512. I hope that the M3 Air is just as comfortable to use in my bed as my M1 is.
And with that M3 Air that I am getting, I want it to last until it fails, or until it no longer gets software support.
