This is how I ended up getting a brand new n800 for a fairly good price on Craigslist (at the time). Some guy ordered it expecting that it was like an iPhone. When he realized it was not a phone, he sold it.

I tried to tell him that he could use it as an internet phone, but he wanted a cell phone.

Really, if you have wireless, you can make calls nearly free. Plus there are all the fun geeky linux things.
