MB v MBP Bigger screen worth it?

Obviously the screen is bigger and runs at a higher resolution on the MBP compared with the MB, but what does that mean in terms of actual screen real estate?

How much of a difference is there between the MBP and the MB? Is it significant?

It easy to compare if they were either a) both screen size or b) both same resolution but cant get a feel for it with having the mix...

Didnt know there was differences between the quality of the screen! (nor the keyboard - not sure that thats actually the case or just the models they have looked at>?)

Interesting review.

There just doesnt seem much difference in actual screen real estate between the two. If the MBP was running at a higher resolution then I could see the benefit but not at 1440 (or whatever it is).
