I pre-ordered the 13" AMD, and here's my 2 cents: In 2013 I bought a MacBook Air. The i7 version was pretty decent for dev, and it had all the other ultrabook niceties (small, light, all day battery, etc). I was still happily using it in 2020, though it was starting to show it's age. In 2023, Apple still makes MacBook Airs in the same form factor. They look almost identical. Several thousand days of active use mine is practically still in mint condition too. If I could pay 2/3rds the price of a new one to upgrade the internals+screen I would totally have done that! I don't expect to change out the modular IO much, but it is nice that I have the option to get an SD card reader or to choose the port layout to match my desk. I've also got what I need to make a magnetic charging adapter for it, so that's awfully nice. So is it worth the extra cost? Maybe not, but I'm an idealist sometimes, and I like their ideals.
