I'm heading off to college in the fall and know for sure that I will be getting a 15" MBP. However, I feel like I will have a hard time keeping all the peripherals (mouse, keyboard, speakers, external HD) organized and plugging them in and out will be a hassle. It seemed natural to me to buy a display and go for the traditional desktop setup which I have always worked on, but I don't know if a 20" or so display will be very useful with a 15" screen on the MBP. However, if I did buy the display I could hook the peripherals up to that and just have to plug the MBP's dvi into the display. Is the extra money for a display worth it or will I be fine with just the notebook's screen? Any alternative suggestions?
