I'd have to see one in the flesh.
I didn't like the last iMac until I saw it for real.
But my first impressions were hmm... well.. actually identicle to how I felt about the last iMac, but without the WOW it looks like some freaky alien type background thought going on...
So overall a bit of a let down.
But then I have a G5 and a 17" G4 so why would I worry.
My other half wants one though.
