I've got a 15" moniter, and do to bifocals, I'd love a 17" flat. I've been working in 960 x 720, an odd size but fills my screen nicely {not compleatly}. The problems might be that some people don't relise that if the program they're using dosen't generate renders in larger sizes, enlarging them in post production just spreads the pixles out losing detail and sutle shadeing. Personaly I like to see the entire picture all at once, other wise it turns into the five blind men trying to describe an elephant.
