I just replaced my 2009 Mac Book Pro for the Brand New i7 2.0 quad core. I have already noticed some issues... 1) When I "expand" movies from iTunes to full screen there are some crazy white lines while expanding. 2) When watching movies in iTunes they usually hang for a second or two every couple minutes. 3) My doc has been constantly freezing while everything else is still operational. Anyone that has the new MacBooks could you please let me know if this is happening to you at all?
