Hey guys i am about to trade one of my N800's with LOTS of extras for a eee pc, and i was wondering if anyone knew a good way
(in U.S.A) to trade items over the internet, to make sure you get your item?

The best way I know of is Ebay. There is an option (or their use to be) where you could setup a private auction. There are also Escrow firms that work with Ebay and independent consultants that do software development. Typically this deals with money for product, but they may have an option to do product for product. However I doubt they will verify that the item is complete or in the condition you requested. More of a "here is a box with stuff that looks like a description" and send it on.

So you might do a search for escrow service or product trade service, and see what pops up.

I would be interested in what you find, choose to go with, and a review of how it worked out.

best wishes
