HP calls this a Power Pack. It consists of
* HP OmniGo connectivity kit
* Digital Writing PDA
* 2 AA batteries
I asked about the Digital Writing PDA and was told that it is some
software that you load onto your OmniGo and it improves handwriting
recognition. Actually, the only thing that the guy seemed sure of is
that it is software. :-)
Call and ask about the free Power Pack. HP will mail you a form which
you mail back. HP then sends you the Power Pack. You need to mail back
the form, your receipt, and some piece of the box (UPC, perhaps, I
don't remember).
