When I was a broke student, I scrouged CRTs people threw out and had a 3-4 monitor setup, but still found myself only concentrating on the middle monitor ignoring stuff off to the sides.

Then I got Apple's nice big 30" cinema display and everything was good.

Then it broke and right after that I started living nomadically with my 1900x1200 equivalent 15" retina laptop and never minded the difference.

I have good eyes after correction and use 9 point fonts everywhere so I can fit a lot of text on screen.
