Windows Phone Thoughts: Do you own one of these Pocket PCs?

I'm trying to compile the most comprehensive battery tests ever done, and I need people who have access to devices that I do not. If you own a Casio E-200, a Toshiba e310, or an HP 568, and you're willing to help me with some battery tests, please respond to this thread. I need a few people for each device in order to share the load (the tests require that you don't use your Pocket PC for several hours). I'm hoping that at least some of the people who respond to this also have access to an external microphone and a WAV file recording program - please indicate if you do.
