I just got my i7 17" and I can't even explain how much of an upgrade this is from my 2 year old 15" MBP. My 15" already looks just plain tiny by comparison, the extra resolution is totally perfect for me and makes viewing large documents so much easier, not to mention how wonderful it is for video and gaming... but the most shocking difference with this new machine is by far the screen. I'm sorry for the few posters who are apparently having problems with their new screens being dim or yellow tinted bit this is easily the most vibrant and beautiful display I have ever seen and I have a very, very picky eye. There are 5 laptops now in my apartment between my two roommates and I and this screen stands miles ahead of even the second closest. The picture doesn't do it justice. In person, the same white images on the two screens side-by-side look completely different. The old 15" looks totally grey when it sits next to the new 17" i7.
