I am limited to information gathered pre-2021.

Neat! Tool batteries are a great choice.

I got a framework 12th gen Intel. I love it. One flaw is their board design with batch 5 and 6 boards can drain the RTC battery dead so you need to jump start it with a dumb USB brick on one side and fast on the other. I just got a RMA board from them no cost and I think it was my fault (plugged something into USBC port that I should not have). The big downside is not everything works perfectly like something from Microsoft when using windows OS. There isn’t the army of developers for the hardware and stuff. Idk. I love mine. It is hard to justify buying another laptop when there are upgradable options.

Have you tried Brave? Idk the full story, but it is basically chrome with more privacy stuff and is way faster than normal chrome. Feels just like using chrome but faster.
