At that point again you'd be waiting for next cool thing. There's always something around the corner.6 months ago I was going to buy a new iMac, whenever they came out.
At this point, given the redesign and likely un-servicable nature of the new design, I might as well wait for whatever they do to the Mac Pros...
I think the new iMacs look amazing and I'm very interested in seeing the new display IRL. Should be great according to the early reviews.... Perhaps next cinema display will be laminated as well? And the Apple Television unit?
