NO ONE WORKS AT HIS DESK ANYMORE, or so it would seem. Jumping on the trend, Logitech has announced a trio of new products designed to make data entry easier on portable devices.The slim MouseMan Traveler ($49.95) hooks to any Windows or Mac OS 8.6 (or above) system, and provides ball-free mouse action using an optical sensor that works on nearly any surface. It\u2019s designed for use in either hand and includes a protective carrying case.The Logitech KeyCase keyboard ($99.95) acts like a case but works like a keyboard for your Palm PDA. The fabric-like peripheral lets you enter data and scroll through screens without resorting to using your stylus. And when you\u2019re done, simply roll up your PDA in the key-cloth and you\u2019re ready to go.If you\u2019d rather have the feel of a more traditional keyboard, then check out Logitech\u2019s TypeAway folding keyboard ($79.95). The thin, lightweight keyboard folds in half for easy carrying and features shortcut keys for your favorite programs. Both the KeyCase and the TypeAway are compatible with Palm\u2019s m125, m500 and m505 models.For more information, visit www.logitech.com.
