Sharp Zaurus 5500
Nice device. I did not find the keyboard very useful, being somewhat cack thumbed. The screen is nice and bright and very sharp. The applications seem to be limited. Though I am sure many at the Zaurus Users Group will argue. The main point is that there is not a good enough, well maintained, central depository of the best and brightest of current zaurus software. The ability to use both compact flash and secure digital (mmc) cards is very useful though.
As a quick contacts database and mobile game platform I found it very useful.
