Those tiny keyboards built into cell phones are like a prescription for carpal tunnel syndrome. Try to keep your hands from getting mangled as you tap out anything longer than a simple text message. As a result, doing serious work on one has been nearly impossible. One solution might be Freedom's Pro Keyboard. It's a portable QWERTY keyboard that connects wirelessly via Bluetooth to your phone. It folds in half when not in use and is small enough to easily carry in a bag or briefcase, weighing about 1 lb. (0.5 kg). The gadget is compatible with most Bluetooth-enabled devices, including the iPad, BlackBerry and Android. Buying one should make it much easier to type an e-mail to colleagues or loved ones. Your thumbs will thank you.
