I have decided that I don't like my iGo bt keyboard, which makes the argument for the N810 stronger. I have an N800. I have also misplaced the gps unit for my n800. I have also had problems reading the N800 screen in certain situations. So, if you can get the N810 for less than $400 (which is what I paid for the N800 a year and a half ago), I would get it rather than the N800.
