I am doing some research right now on the best mobile linux device I can hook up a web cam too. Basically all I need is a USB host and linux. I have looked into gumstix and they are exactly what I want for the size and features but I am looking for any other advice.

I thought about my friends N800 and I think that is right in my price range and has a nice screen and keyboard. So questions arise, does the N800 have a USB host by default? Does it supply enough power for a web cam? Could I use a USB hub to hook up a USB GPS device as well?
