dbarron Not at all the case with me, but I wouldn't expect perfection given that I do a lot of dev & experimenting (although a few times it was just about version differences). The Solus team does seem to have a pretty strict software repo adoption policy though (correct me if wrong?), so this may never change.
I'm planning to provide a Solus Budgie install as the default OS for the next PC I build for the parents, and one potential issue I see is the lack of auto updates. I'm not sure I can get them to check for these even in the Software Center regularly, so it might be 1-2 updates a year if that doesn't happen... Still better security than Windoze I guess, but it does make me wish there was an "auto-update" option (preferably configurable at install time so you don't forget).
However, shouldn't be an issue for a new-to-Linux user willing/wanting to try Solus first if they're going to the trouble to install themselves. And then again, do other distros like Mint even have an automatic update option? Hmm... maybe it's not an issue period?
