Upgrades : Palm Universal Wireless

Keyboard is compact. Difficult to fold and unfold at first, but once you know the sequence, it is easy. Initial programs to install driver on Tungesten E, but after several attempts, it worked. You have to go to the keyboard icon on the PDA and turn it on each time you want to use the keyboard. Uses pair of AAA batteries. Good battery life - while I only use it once in a while, 9 months later they still show 3/4 charge. Uses IR port. Looks solid, no breakage from getting hauled around, though I am fairly careful with it. Sometimes doesn't work - maybe due to less than 1/2 charge on the palm E. After recharging Palm, keyboard works again. Hide Full Review
