While there are those who consistently shout from the rooftops about how the PDA market is dying, Gartner has reliably highlighted how the category–it defines as a data-centric handheld computer weighing less than one pound with two-handed use in mind–is surviving, if not thriving, because of the addition of cellular-wireless capabilities. By Gartner’s count–and definition–2005 was a banner year for PDAs. Worldwide shipments increased by 19 percent from the year before, to a record 14.9 million units; the best tally since 13.2 million in 2001.
