I've been pure linux at home for several years now and can't ever see myself going back to a M$ OS - I was gonna take a look at 10 - cos initial reports were sounding promising so a duel boot on a spare HD wouldn't hurt. The you shalt not chose your updates happened. The data slurping etc. Now they won't tell you what the updates they force on you actually do?
F*ck that tbh.
Linux does all my needs - especially now Valve have made steam Linux native and the few games that aren't on linux wine takes care of - a previous poster mentioned WoW - works just fine under Wine.
My 2 cents
