Willcom D4 is a UMPC (UltraMobilePC) about which we talked about a while ago because it is one of the most little devices in the world being able to run Windows Vista. It was released a while ago but I did not have the chance to use until last week, it IS little… but it is much more bigger than I thought. The keyboard is so big that is difficult to type using it like a PSP, and I have pretty big hands!
