If you were looking for a large and impractical "cellphone," we just might have some news for you. Hot on the heels of a certain Dell netbook mod, we submit for your approval a 5-inch convertible device that features a QWERTY chocolate keyboard, trackball, and quite possibly Windows XP. We've got no relevant data for you, such as manufacturer, price, and release date are all mysteries at this point, but you can see it in action if you like -- just check out the videos after the break. As for us, we think we'll just wait for the xpPhone.
