I've seen and tried Win8 at a number of trial kiosks set up in shopping malls around the world. I'd much rather use XP. The only reason I'm on Win7 now is because when I last upgraded my PC and laptop and went to install XP, I found that the disc no longer worked. The very first thing I do on an new install is revert the interface back to the Windows 2000/XP "Classic" version. Otherwise it simply isn't useable.
I don't want "Shiny" and "Flashy". I want functional.
