i am the same way i cant tell a differnece between the screens of my ipod touch 3rd gen and my iphone 4 8gb model so i think its all hype untill i see the difference myself in the macbook pro line
As a recent owner... I can say its very much like buying good head phones... on the way up I found I couldn't tell the difference... now I look at lesser screens and I feel like the spanish inquisition is going for my eyes!!!!
