AvantGo, Inc. released results from its 2003 Mobile Lifestyle Survey–delivered to users on their mobile devices to determine their preferences, buying patterns, interests, and activities. The survey sought to uncover trends among those who regularly carry and use a personal digital assistant (PDA). The results may surprise brand managers and marketers looking to reach that key male, age 25-50 audience. The study found that mobile device users in 2003 are mostly male, well educated, and well paid with varied interests in sports and travel, for example.
