One way to choose is to go to the apple store, and to see the condition of both, chances are your will come NEAR to it, not exactly (since they're treated like crap), but will eventually come to a condition near it, and it will take a while, and then decide which you like. new penryn blackbooks are to be less prone to fingerprints, and the blackbooks dont look THAT bad to the bad compared to the white books that are brown, as in the keyboard, and i'd rather do less maintenance on my laptop, so looks like the black tax is worth it.
