[bearfartinthewoods]

i don't keep up, i'll admit it so i haven't a clue as to which gadget i need.

i need a portable gadget to manage inventory.
basicly the ability to have a spreadsheet with 200 items with three colums each and an adress/phone book.
stand alone....no downloading necessaey.

do they make such a thing?

thanks in advance
