Those 27" iMac display issues? Um, yeah.
Colleague turned this brand-spanking-new 27" iMac on, straight out of thr box, and BAM! - instant blue screen down the left hand side.
Here you can see it running the screensaver - while it still (sorta) works, it's definitely screwed. And that's not even the worst part - being a CTO model, the client had been waiting a while for this one as well... :S Certainly not the greatest product launch, Apple.
