Anandtech posted a review on the 27-inch Apple iMac
A couple of weeks ago, a big box showed up at my doorstep. Inside? The new 2011 high-end 27-inch iMac. More or less it's the 2011 MacBook Pro mated to a 27-inch LED backlit Cinema Display. It's basically my personal setup but in an all-in-one desktop.The 27-inch Apple iMac Review (2011)
I never liked the iMac. I understood the appeal, but it wasn't for me. The CPUs and GPUs weren't fast enough, there weren't enough drive bays and the display was always worse than what I already had on my desk. However the same series of events that allowed me to dump the Mac Pro and use a Sandy Bridge MacBook Pro have made the iMac that much more interesting.
