There are actually issues with Windows XP, the only thing is that IMO people learned how to work around those issues. I think UIs should either change very gradually and only in ways that literally are better, but also have a way of ensuring the options aren't removed entirely, or at the very least if the option is obscure ala options removed in Gnome 2, then they should be kept and allow someone to create a tweaking tool to change them. If a huge change is to be made, like the Gnome Shell, then it should be done in a development release and ALL of the compatible UI should be kept on the desktop, with an easy UI option to switch between the modes. It turns out that Gnome Shell could do this - but only after a time. UX and UIs are one of those things you really should be incredibly careful about foisting on anyone. If you do it, you need to do it somewhat gently.
