Just FYI, while the latest keyboard drivers from Palm are 1.5 for the foldable keyboard....
ThinkOutside, the company who actually makes it, has version 1.6 on their web site, which supports all brands of the keyboard, and all palm os models.

Great new version. Seems a bit more reliable, layout support, and an on screen cursor, which is actually pretty good when you are typing something and don't want to pick up the stylus.
