Considering that this is a Mac forum, what answer would you expect? Of course you should get the MacBook. You will not be disappointed, and you will not pay more for it than you would for a comparably equipped PC laptop.
Of the MacBook models, I think the high-end white one is the best deal. Budget an extra $100 or so for some third-party memory so you can max your RAM at 2GB.
You'll have a great machine!
