If you're still in the Herndon area, MicroCenter in Fairfax has the N810 and N800 in stock last time I was there - which was about a month ago. Here's a link to the store info and the phone number:

(703) 204-8400

Call them up and see if they still have them. Price might be higher than the best online deals, but at least you can walk out the door with one in your hands!
