and I've never owned an Apple before or have worked with OSX. I'm looking forward to the change. I'm mainly getting one because I play guitar and have heard great things about Garageband. I also major in computer science like to tinker around with things... Anyways, I was wondering that if I get an external DVI monitor for my powerbook, would I be able to set the laptop aside, still on of course, and use a bluetooth keyboard and mouse to work on the external? Or would am I limited to using the PB keyboard/touchpad...? Also..I'm really planning on just getting a slightly used one on eBay, this way I have enough money to get a 20'' external. Should I wait until the new and improved ones come out so that the soon to be older 1.33's come down in price even more?
