> The latest t14 received a better score from ifixit than framework for repairability (first ever to get a 10).

Hm, I wish they had scores for the X230 and older; I'd like to see how they compare. IMO they're better, if nothing else because you can replace RAM, SSD and battery without unscrewing the entire bottom.

I don't think the difference between half the bottom and entire bottom would make a difference according to ifix it. It's more about: 1. Is it possible 2. Is it documented 3. Do you need proprietary parts 4. Without solder
