A total of 2.44 million handhelds were shipped in the third quarter this year, compared with 2.59 million in the same period last year. The number of shipments continued its sequential decline, down 7.1% from the second quarter, the third straight quarter-on-quarter drop.
Palm leads the market with 33.8%, up from 29.1%. Sony and Toshiba, both comparatively recent market entrants, also showed strong market share increases. Sony is now the world's second-largest PDA vendor with 14.4% of the market, up from 3.6%, and Toshiba is number four with a 4.3% market share. No data on Toshiba in 2001 was provided.
Other vendors have fared badly, according to IDC figures, notably Casio and Hewlett-Packard, which saw their market share decline from 7.1% to 4.1% and 12.4% and 11.9% respectively.
IDC expects PDA shipments in the fourth quarter to match last year's fourth quarter or be slightly below that figure.
