Probably not the place for a general discussion, but let me add my bit:
(1) I use the old "digital diary" and a desk top.
(2) Somehow, in this context, hand helds (or Pocket PCs as the Microsoft versions are called) seem to fall somewhere in between.
(3) Having said this, the only advantage I see seems to be the note taking ability (specially with a back-lit display).
(4) But then, does any one know of a hand held which comes standard with IVR (interactive voice recorder or mike) capability also. This alone I think would make "note taking" complete.
As you can guess, I don't know much about handhelds.
Please clarify and point me in the right direction.
End of mail.
