I'm about to buy an apple powerbook (it'll be my first apple computer!) but I need a little advice. I was thinking of getting the 12" with superdrive, but I came upon a great deal for a 17" but I'm afraid the 17" might be too big for my liking. Sure, I've played with them at the store but it's not the same as owning it and carrying it around to really get the feel for it. Any students out there have the 17" and still have great portability with it? I like it because of the bigger screen but it's not absolutely necessary since I won't be doing any video editing or anything like that. 12"... or 17" they both have the same specs. 1.5ghz superdrive 512RAM (that i would eventually upgrade) etc... Let me know what you think!
