I did and as a long time PC user (still am as I have many dollars invested in PC Music/Audio programs)....and to me Vista is a long way from reaching the quality of Mac OSX. The new conroes are out and hopefully these will trickle down in price to MB, MBP and desktops while the likes of cross over make headway allowing me to salvage and more completely to 100% Apple in the next year or so. What say you? My Vista experience was uneventful. When you get used to thinks like dragging folders onto other HD's, DOCK, expose, you really miss it when it's not there. Sure you can get 3rd party apps, but nothing comes close to iLIFE from Microsoft. I think they have a lonnnnnnnnnnnnng way to go.
