I'd suggest you skip all the win products *period*
Heh, but seriously, you want a better OS, use the new iMacs -- I've got a PC running XP, ME, 98, and mandrake but for designing (my profession) I always use an iMac -- more stable.
And, my primary OS on my PC is mandrake, but second to that is ME, I find nothing worse about it (compared to the rest of the windows versions).
Besides, haven't you seen the new "switch" commercials?? (hxxp://www.apple.com/switch).
