I do a lot of video editing and have a lot of stuff on my MacBook Pro that I wouldn't want to lose. How do I back up all of my files so when I get a new iMac I can simply restore it all? Can I buy an external hard drive or do I have to settle for Apple proprietary stuff? I'm mainly thinking of switching because this is a Core 2 Duo MBP w/ a 13 inch screen and it simply doesn't cut it for the video work I do. Exporting a 7 minute HD video should not take damn near 40 minutes lol. The added screen real estate and speed should help out immensely, I would probably just get the base $1,199 21.5 model.
