The major benefit of using the HalfKeyboard is that you can use your stylus seamlessly while typing. Your right hand is free to tap, tap tap...which we all know is half of the data entry process on a PDA. This feature alone makes the HalfKeyboard worth looking into. The Stowaway does not have this feature. When I use my Stowaway I'm constantly docking my stylus in either side or holding it in my mouth. That's a real pain. Granted, if you are in the habit of writing novels on your Visor, this may not be the keyboard for you. But if you are looking for a keyboard that is small, really portable, functional, and easy to set up, the HalfKeyboard is a valid choice.
