I went from a hi res Macbook pro 17"(1200 on the short side) to the NEC PA271. The color and contrast are way more accurate than the laptop is, although the laptop was adequate to see sharpness and detail. I got the "SV" option(more $$$) that has an extremely easy to use automatic calibrating device that is nice.
Supposedly EIZO monitors are "better", but the NEC was at my absolute top floor in price.
