However, the Zire includes older versions of the application “Calendar” and “Address Book” that were on the original version instead of the new more comprehensive programs “Agenda” and “addresses” that fit the latest Palm Tungsten models.
The most notable improvements include faster processor Texas Instruments OMAP 126 MHz, which considerably increases the reactivity of the unit, and the swollen memory 8MB While it may pale compared to the Palm of the moment, but is not here a media assistant. In addition, 7.2 MB of storage space available give space to add more applications and store thousands of contacts.
