The Meazura 1000 has a black and white LCD screen.  It was available with and without Bluetooth.  To see if the PDA has Bluetooth, start the Prefs application and look for Bluetooth in the menu at the top right corner.


The Meazura 1000 also has a CompactFlash option which adds nonvolatile memory storage for applications and data.  To see if the CF card option is installed, click on the menu in the upper right corner of the main desktop screen.  If the last item is Card then it is installed.


The Meazura 1500 has a color screen and a much faster processor.  All of these have Bluetooth and a Flash memory SD card.
