I'm kind of in a quandry as to amking a mobile purchase. I like having alot of screen real-estate (like haing my windows visible, at least in part, so i'm leaning toward a 17" PB. But its SO big, that i was thinking maybe a should split for a 12" PB for mobility and get a refurb 20" cinema display for use w/ the PB @ home. Currently I have a humble eMac 700.
