I have a first generation framework 13, I upgraded the mainboard last year to the 12th gen intel i7-1280P mainboard. My original mainboard was from the first batch with the bios battery issues but still works, though I haven't had success getting it to run standalone in the coolmaster case yet.

I'm happy with my framework 13 four years later. I might switch to the stiffer hinge and/or a matte screen in the future. Might try one of the AMD mainboards in a few generations when they're cheaper and put my current mainboard into another case...

Edit: FWIW I bought a macbook air M1 a year after getting the framework 13, and ended up selling it. The battery life on the macbook air was significantly better, but I can still spend an entire workday in the park with the glossy framework 13 without needing to recharge so the extra battery life from the M1 didn't really have a ton of value for me.
