It's been my impression that as serious capability upgrades are
introduced to the PDA software, the hardware requirements grow with it.
As a result, if you bought a PDA solution 3 years back, and wanted to
upgrade the software now, wouldn't you find yourself upgrading the PDA
too?


Yep, but a top of the line PDA today is $400. Your old one will fetch
$100-150 on ebay.
