I have my main gaming rig with 7 on it and a laptop I bought a few months ago running 8
8 drove me nuts for the first week (why hell is 8.1 an optional update?) Like the motion gestures on the track pad... so annying when playing a game and i graze the pad with my arm to bring up the metro UI (makes me laugh they bassicly added a third windows key) I've gotten used to it now but it's still a chore to find stuff so I'm glad to read their changing the control panel to resemble the older style and the new start menu looks great.
If it is free to 8 owners and it impresses me enough I may consider an upgrade for my desktop
