Besieged by competition from mobile telephones and other wireless devices, worldwide shipments of handheld computing devices declined 2.2 per cent to 2.2 million units in the second quarter of 2004, down from 2.27 during the same quarter in 2003, according to research from IDC.
The market for handheld devices, also called personal digital assistants (PDAs), has been in decline since 2001, hurt by a general slump in technology purchasing, competition from wireless devices that perform PDA functions, and by a lack of new applications, IDC analyst, David Linsalata, said.
"The handheld of the 1990s is the same as the handheld of the 2000s in that it hasn't really evolved," Linsalata said.
In a sign of the slowdown, the third-ranked PDA vendor, Sony last month decided to exit the market, except in Japan, leaving HP and PalmOne with more than 65 per cent of the market between them, according to IDC's numbers.
Sony, which ships the Clie handhelds, saw its market share drop by 33.2 per cent in the last year. The company shipped 172,000 units during the second quarter.
PalmOne had the largest volume of shipments, selling 924,000 devices in the second quarter, down 0.6 per cent from the same period in 2003. Following Sony's departure, PalmOne remains the only major PalmOS vendor in the market, IDC said.
HP's shipments increases by 39.2 percent year-over-year. it sold 530,000 devices during the quarter.
