My C434's battery is starting to show its age (compounded by the fact that I hardly use and thus constantly forget to charge it) so I'm looking into what I might replace it with. So far the most obvious choice is Framework's option, I like the concept and would love to support a company like that, although I can't see it sticking around long-term - it's a niche model by a niche company supporting a niche OS. Still, even if I only get one nice Chromebook and the option of easily pulling the main board out to use as an SBC outside of its useful life, that would be worth something to me.
I don't think the transforming form factor is really for me, I've never used the ability to hold my C434 like a tablet and have used the ability to fold the keyboard underneath it maybe like twice. Maybe I would if I had one with larger bezels and speakers in a less dumb place, but... I don't!
