Thanks!
Thanks for your informative response. I didn't realize that there aren't standards for the DIA. Hopefully with Palm finally releasing a PDA with a DIA, other companies might start using their DIA instead of their own. However, I don't know if PalmOne or PalmSource is the "source" of the new DIA and I have my doubts that Sony will use Palm's DIA.
Anyway, thanks for the detailed response and I'm looking forward to using a non-beta of Fitaly on my new T3. Any other input method for me pales in comparison. Thanks for such a useful product!
