I'm Happy I'll stick
Green Granite what version of Vista were you running? I have Vista Ultimate 64Bit SP1 and it seems pretty good moved on from XP Pro which I really liked but to be honest it took SP1/2/3 to iron out all the bugs and still there were the odd one or two even in that OS.
No point in me jumping to W7 if it doesn't gain me a whole lot me thinks be interested to see how its accepted by the masses when it is released to market later this year.
