Hey, Just bought myself a BRAND NEW 20" iMac from Mac Store in Sheffield. Pictures here - http://www.flickr.com/photos/wasim931/ I just noticed, theres a white blemish on the screen when I open FrontRow when the screen goes black. Theres a small chip of the plastic on the top right hand corner. And FrontRow and other stuff is really laggy, my 15" PowerBook is better than this. I'm going straight to the Mac Store tomorrow and demanding an EXCHANGE! What do you guys this of this?
