The Handspring Visor Prism is the first infinitely expandable full-color handheld computer. This pocket-sized wonder displays over 65,000 vibrant colors so everything is crisper, brighter and easier to read. And, with the unique SpringboardTM expansion slot, you can snap in a digital camera or global positioning system and instantly view full-color photos and maps. Best of all, its plug-and-play so there are no drivers to load. Just snap in a module and it works!
