I run a Thinkpad and my partner is an early adopter of the v1 Framework. She had quite a few early adopter issues on her leading me to believe the hardware polish isn't there 100% (eg hinges too weak they had to release an upgrade, this broke the display cable and led to BIOS issues, etc).
I mostly agree, the one place I think Thinkpad could use more maintainability is in mainboard compatibility. Framework promises (TBD) Mainboard compatibility across upgrades, we'll see if they deliver.
