I cant speak for Palm Inc but since they have aquired an OS company, and to be more specific a Media based OS, it is plausile that Palm Inc wants to use that OS on their devices and make them more media enabled, as well as more network enabled in order to be able to compete with the PocketPC platform. Even though Palm Inc has a big footing ahead of the PocketPC market M$ is making their OS better, and companies like compaq are making some nice devices which in the future will probably temp users to move over to the winARM side of PDA computing.
On an online demo, along with handwriting, the PocketPC OS can also recognize Graffiti glyfs which gives you an idea of winARM's target.
