I'll just preface this by saying that I've got a 17" MBP and the PPI of this is 133 vs the 135 of the 11". However, I've noticed whenever I've been using the 11" that the text, to me, is very difficult to concentrate on. When I bought the machine, I added the macrumors color profile, and whilst this definitely made the colour reproduction much better, the text was still quite a challenge at a normal viewing distance. I do not have this problem whatsoever with the MacBook Pro. Does anyone else notice this? Is it a contrast issue?
