I'm also halfway trying to talk myself into taking the plunge (admittedly not with windows, I spent a good bit of my career locked into it and I'm done lol).
You seem open to share some details, by which I mean, I feel less potentially rude to ask - care to share how long you've been working with em (the Frameworks)? And any details therein, how it's been, any frustrations?
Longevity matters a lot to me, at least in the medium term (and it's not lost that me buying their ish would help them do that in a tiny way lol), so I'm gun-shy. My current approach is simply to buy old business class Dell things for my household, there's ~no chance I'll find myself unable to buy parts cheaply. I do also treasure giving old machines further life, very sustainable, feels good.
Whatcha think? Time for me to upgrade my approach (slowly 😅), or best to wait it out a bit and see what develops?
