is it possible to run two monitors from a mbp? i have a friend who is considering buying one, but he really wants to be able to drive two monitors from it (i don't know why). that seems to be a deal breaker for him for some reason. he uses an ibm laptop with a dock - he can plug one monitor into the laptop and another into the dock and then have 3 indepent screens including his laptop. is something like that possible with a mbp?
