USB host would be such a killer feature on the N900, shame Nokia didn't include it... Think of the possibilities: - Plug in your real camera and upload photos you took with it. - Copy files from a friends disk-on-key without needing a computer. - Plug in a printer (is it possible?) to quickly print documents you have on your phone. I honestly don't know if all the above are possible, but if they were, and the next N9xx had them, I'd never consider another phone again.
