This is epic. Last year I had a 24" iMac that died. I brought it to the Apple store for repairs, turned out to be the video card. The repair operation snowballed into total failure and they ultimately replaced the machine with a 27" core i5 quad. The 24" was less than a year old at that point; the 27" was built in late 2009. Seems the lifespan of these things is less than a year, at least when they're at my house. Last night I was reading some RSS feeds, banging out some emails and then *poof* the machine instantly powers down. Power glitch? Nope, and besides, it's plugged into a UPS. Either the ATI4850 baked itself like it did in the 24" or the the power supply went or god knows what now. Whatever it is, I'm at my wits end. Needless to say I have a "genius" appointment, which is in less than an hour from now -- the same clowns that failed to repair my 24" properly. Hopefully they'll fail again, and just replace the machine. At this rate I'm due for a new iMac every year.
