Computer Alliance have a special on their Asus UX31A R4003P (and also the i5 versions) at $1595. Next cheapest on Staticice is $1699. Umart had it at a similar price a few weeks ago but sold out.
If you're thinking of buying this, bear in mind that they are about to be superseded by a similar model with touchscreen and 8GB memory(which will probably be around the $2000 mark). Don't know when this will be though.
