The one-handed FrogPad Mobile Keyboard can replace your current QWERTY keyboard with only 20 keys and a 5.5- by 3.5-inch frame. You can hook it up to a PC, a PDA, or any device with a USB connection. The keyboard's size makes it easy to travel with; each key represents up to seven different characters. You can switch among number, symbol, and CapsLock modes using a series of buttons that line the bottom ridge.

For efficiency, the Spacebar is located near your thumb, and the vowels are wheeled around your index finger. The most commonly used letters are placed around the strongest fingers. But this board takes some time to master. If you do master it, travel will be a snap. Look for a FrogPad keyboard with Bluetooth in 2004.
