I am almost set to buy a 17" iMac C2D for my wife, but want to know if anybody knows how the display quality compares to that of the 20". Of course, I would really like the larger screen, but have a hard time justifying the extra $300 (I don't think she will ever need the larger hard drive or other differences). I know from direct comparison that my Dell 2005fpw is far brighter and clearer than my 17" iMac G5, but I don't have any comparisons to the new Intel line. Does anybody know the answer?
