In two and a half years I believe my iMac has just properly crashed for the first time. I mean properly crashed, left stranded on the side of the m25 with no spare wheel and a dead phone battery!! It’s funny as when I purchased the glorious machine the very helpful mac guy said they recommend upgrading every 3 years. He clearly knew something that I didn’t back then. Probably never try and open Image Capture whilst running iTunes, safari, iCal, address book, logic, dropbox, pages and most importantly Stickies in the background!!
