MacBook...2.0ghz...awesome!
just my 2 cents.
You might be well advised to wait, as others have mentioned, until MacWorld in Jan, just to see what happens. Also, order it with the stock 512mb of ram and then purchase 2 1gb modules (total of 2gb) from somewhere else (apple is overpriced). I've found that OS X just doesnt function well with less than 2gb these days...although I'm sure others may disagree.
