LifeDrive and Fitaly are currently Incompatible.
I am being told that a large number of applications work in a reduced fashion -- that is, they may work as long as they don't have to interface with the DIA. At this stage, my advice would be to get a LifeDrive ONLY if you only work with standard applications supplied by PalmOne. For others, it may be better to wait a few months before you buy a LifeDrive until the dust settles... and PalmOne ends up publishing the information needed to adapt to the LifeDrive.
In our case, we are going to await this information and will not engage in costly reverse engineering as we did for the T3. We are currently fully booked on Instant Text Mobile and adapting it to the Pocket PC. We have time left for porting to the LifeDrive with the appropriate information but not if this involve sleuthing to discover it.
