hmm, Id recommend something a 14 inch widescreen or 15.4 inch widescreens. Unless you are going to plug those guys into 19+ inch monitors I would not bother plugging a monitor to those.
Asus is having a nice collection of new santa rosa models, have a look:
I think you could find one in your specs. Make sure you get a nice resolution on the screen (ie. WSXGA) The Asus G1 is pretty nice but a bit bigger than regular 15.4 inch...
