I go get my 12" pb today (yay! i can sleep tonight) but i dont know what i need to have since i have never had a laptop before. I have an old corded mouse and crappy keyboard that i can use as an external for a little while, but what cables/adaptors are good to have with an powerbook? I know i need a case but there are so freakin many i cant pick one! Any advice would be very appeciated!
