The Stowaway Infrared Wireless Keyboard is the perfect universal productivity companion to your handheld. The compact, collapsible design is unique to the Stowaway Infrared Wireless Keyboard and allows it to fold easily to become the smallest full-size Infrared keyboard on the market so you can take it everywhere. An integrated cradle and adjustable IR wand ensure consistent alignment with your PDA infrared port even in landscape view mode. Because it uses Infrared instead of a physical connection with the PDA, the Stowaway Infrared Wireless Keyboard is universally compatible with a wide range of current, and future handheld devices.With its genuine full-size 18 mm spacing between keys, the Stowaway Infrared Wireless Keyboard allows you to quickly type email, memos, and reports in optimum comfort. Punctuation, symbols, and international characters are easier to find and type than handwriting recognition software.This keyboard is Compatible with following PDAs and Smartphones:HP iPAQ: 1900, 2200, 3600 3700 3800, 3900, 4100, 4300, 5100, 5400 5500;Palm One: m125, m130, m500, m505, m515, i705, Zire, 21, 71, Tungsten T, T2, T3, C, E, W;Garmin: iQue 3600;Handspring: Prism, Platinum;Dell: Axim X5, X3, X3i;Toshiba: e330, e350/355, e740, e750/755, e800, e405;Sony Clie: SJ20, SJ22, SJ27, SJ30, SJ33, SL10, T400, T415, T425, T600, T615C, T625, T665C, NR70, NR70V/U, NX60U, NX70V/U, NX73V, NX80V, TG50, TJ25, TJ35, UX50, TH55;Handspring: Treo 600;Nokia: 6600, 3650 (beta driver), 7650 (beta driver);HTC: XDAI /MDA, XDAII;Kyocera: 7135;Samsung: i500, i700, P800;Sony Ericcson: P800 (beta driver).
