In any case, the Prism has a beautiful display. The screen is pretty much useless in sunlight, but if you mostly use your Palm indoors, you'll find the Prism's screen to be very good. The Prism is faster than previous Visors, with a 33MHz processor. The back casing has a contoured region near the bottom. As a result, the Prism's cradle is different from the cradle used by the other Visors.
Battery life is quoted as six hours of continuous use.
This can be extended by reducing the brightness of the screen. Holding down the power button for about two seconds will pop up a dialog box with a slider control for setting the brightness level. I use my Prism heavily, and estimate I could get maybe 3 days on a single charge. Since I have a cradle both at home and at work, it's easy to keep my Prism fully charged. A travel charger is available, so you can charge it on the road without lugging the cradle around.
