Worldwide sales are down 12.1% on the same period last year and have plummeted 25.4% since the last quarter of 2001. However, this still represents an estimated market of 3.25 million units.
Palm is maintaining a substantial lead over its competitors, with a 39% share of the market, but the Microsoft PocketPC champion Compaq iPaq continues to gain ground, especially in Europe.
The iPaq, which is expected to oust the Hewlett-Packard Jornado PDA if the merger with Compaq goes through, accounted for 10.1% of the market, rising above the Palm-based Handspring's 9.9% share. A possible reason for the switch in positions is anticipation of the Handspring Treo, a wireless-enabled PDA phone which may boost the company back to the second slot.
Among the also-rans is the Linux-based Sharp Zaurus which lies below Sony at fifth in the IDC listings.
