I'd suggest going to Costco and getting either an 8 gig one, or an external hard drive. I'd you buy a new Mac laptop, the spoke apple store will transfer data.
If you want to get a PC, the new Micorosft retail stores are GREAT. you can get a machine WITHOUT. A bunch of Preinstalled bs on it, and they'll transfer data as well. You'll still have to reinstall apps tho.
