At first I didn't think too much of this when I saw it. It looked much like the fabled Foleo from Palm although a bit more plastic and less robust. Then I started to think that it could in fact be a bit more interesting, as according to Brighthand it extends the Windows Mobile device not just be adding a bigger screen and keyboard and mouse, but also USB ports. Now, that could be a little bit more interesting, as it could be fun to extend the use of some of the best Windows Mobile apps via a keyboard?
I'm guessing that the apps might have to be adjusted to accept a USB keyboard, but it is a nice thought nonetheless.
