Im going to be buying a seperate monitor for my 12 inch powerbook (1.5,512,64 vid) from newegg (apple displays are way too much money). I would like to get a 19 inch display but am not sure how well my PB would work with it. I am hoping to use it as dual display so what size would everyone recomend or what size do they currently use (17,19, dual display or just the monitor). Thanks!
