I've been trying to decide between the 15" Macbook Pro or 17". Are the screen qualities on them the same? The resolution/dpi. I can't seem to find a clear answer on this. My friend bought her 17" in the Apple store and told me she got the HD version. Is that availabe for the 15"? Also has anyone bought the 15" 2.2 and wished they went for the 2.4? I'm finding that they say there isn't much difference. I'd be using it for CS3 and After Effects (short animations). Thanks for any thoughts.
