Query: AXIM PDA X51v

This is a neat unit, purch from Dell 11/05, with the Blue tooth Keyboard. Great display. I installed a SD card. Only problem is the battery life, the thing goes dead in a day or so when on the shelf. Then it has the "white screen" thing, do a soft reset, and back to normal operation. Might get a bigger bat. BUT--I have a PALM Z22 for etcetera, the battery seems to last FOREVER. ADVICE!! take a pass on the PDA thing and get a Palm Z22 for every day notes and little stuff.
