Report on Growth in Wireless Handheld Market Flawed?

According to Gartner, wireless PDAs are mainly used for data apps and typically are operated with two hands. Smartphones are used for voice and operated with one hand. But in an era when voice and data are rapidly converging, this distinction seems arbitrary.
