According to research firm Gartner, BlackBerry PDA shipments grew by 52.6 percent in the third quarter of 2005.Insofar as what Garnter terms a "PDA," they set the standard as a data-centric handheld computer designed for use with both hands, equipped with instant on-off capability and a variety of third-party applications.
That covers the BlackBerry 7200 series (like the 7270 you see over there) but not the 7100, which is more like a cellphone.
Insofar as leading operating system vendors, Microsoft leads with 49.2 percent of worldwide shipments. BlackBerry-maker Research In Motion is second with 25 percent, followed by Palm OS with 14.9. Symbian and Linux brought up the rear.
