BeOS went under.
Ed: I was a huge apple fan, bought an apple clone from Power Computing. Then Apple revoked the licensing that allowed all the apple clone companies to exist. That’s when I went to BeOS which would run on my clone, and got a multicore intel machine too. When BeOS went under I tried Suse. Had kind of a sucky UI in my opinion, but I hung in there with linux as an alternative to windows and went Ubuntu/Debian/Arch/Nixos and I’m still on nixos now. Its pretty much my exclusive OS since I quit my job that required windows 5 or 6 years ago.
No more tricky than windows these days. Nice thing is there’s a lack of commercial BS - spyware, ads, unwanted apps etc. And pretty much no matter how old your computer gets, you can still run brand new linux on it.
