I bought the Diet and Exercise Assistant and after playing with it for
an hour or two, dumped it. I regard it as poorly designed, slow,
unintuitive, difficult to use and basically not worth the space and
processor time it takes. Other (less exacting) users might not have as
many problems with it.

I ended up loading Fitday onto my PDA using a WIN/Dos emulator running
under a beta Linux install. (http://tinyurl.com/lahvp) A bit buggy on
occasions if I run too many other simultaneous apps on the PDA but still
more stable than most Windows boxes. You need a modern PDA with a fast
processor and plenty of memory to do that. Fitday runs on my PDA at
about the same speed as an old Pentium 3, not brilliant, but fast
enough. My PDA Fitday file auto-updates itself to my main computer every
time I come within Bluetooth range.

I have no idea how good Health Fit Counter is, I have not seen it.

The older PDAs aren't powerful enough to run an emulator, at least not
in Windows mode, they can run DOS, though I haven't seen one running
Linux/unix.
