Avantgo said other characteristics of those who answered the survey include:

-- They come from a variety of industries, and the majority of these PDA users own both their homes and their cars. However, nearly a third are in the market to purchase a new vehicle in less than one year.

-- They travel for both business (with 12% averaging more than 10 business trips a year) and for pleasure (with 24% taking over three vacations per year).

-- When they aren't traveling, they are busy using wireless services from a variety of carriers and a combination of their desktop and laptop computers to conduct online purchases of books (60%), PC software (56%) and CDs/music (49%). In the next six months, among the items they intend to purchase are new PCs, appliances and cameras.

-- They all own a PDA that almost two-thirds purchased for themselves, while others were a gift or provided by their employers.
