I bought white and definitely like it better after using both, though yeah, it's just personal preference.
Only 'catch' with that is...is the white one less "manly" if you're a guy? I don't know for sure if it is or not, but the black one might be a slightly "safer" bet if you're worried about that, which could be an issue at your age, since people are jerks at that age.
Also, while again this is personal preference, at your age money was SUPER tight for me, and the iPad wouldn't have interested me much next to the game systems and (if it were now) an iPod for podcasts while doing boring stuff. Though obviously that may not be the case for you.
