Foxit Software recently released an evaluation version of Foxit Reader V1.0 for Windows CE

This PDF reader application was specially designed for Windows CE devices running Windows CE 4.2, 5.0 and 6.0. The evaluation version does not allow you to access all of the features available in the full version, but does give you an idea of the potential of this software.

It is my impression that Foxit Software is trying to get a feel as to whether there is still a market Windows CE software, so if you are interested in a quality PDF reader that runs on your Handheld PC, you might want to try this software and drop them an encouraging e-mail.
