don't do it. you'll only hate yourself the next week when the next series of processors come out and your model has been reduced by $600

But seriously, if that is all you are looking for size and power, you may want to check out the either the Winbook X2. If you are looking for price, you may want to look at some of the Compaqs at Best Buy/Circuit City. Decent selection, decent price and will do what you want.

However you may also want to look at some used ones. It sounds like your requirements aren't that heavy that you would need a powerful box. Since they depreciate like 50-60% very quickly, you may get a good deal.
