The problem with the battery is that it’s glued in and requires basically destroying the foam it sits on, with no available replacement for the foam or specifications given AFAIK.

Also, if we’re just talking anecdotes here, I have at least two Nintendo devices from the 2000s that ended up with swollen batteries. This has actually reminded me that I might need to check again.

I mean, it’s clearly not meant to last decades given the battery situation.

I’ve heard of some blockchain based systems referred to as decentralized cloud before (including stuff like Sia and Storj, which I guess is what OP wants). I haven’t looked into them that much, but IIUC they push most (all?) controls and so on to the edge. I’m not sure I’d use them though since the networks aren’t super large.

Shopping online locally or just finding certain items? It’s not great locally because it doesn’t seem to use your location for searches (which is good IMO), but it’s usually been fine for me if I’m just looking for something I want to buy. Note that you need to tune the results for them to be good (you can adjust site rankings for yourself).
