I have a 17" Powerbook and I don't understand what I am supposed to notice in the new 15" Macbook Pros with the same resolution. I have seen them in person and I can't tell the difference. Does it feel like you have more space in a new 15" compared to the 15" Powerbook? SO its just smaller pixels and thats it, everything just looks crispier? Am I supposed to feel like I am on a 17" Powerbook when I am on a new 15" Macbook Pro.
