There's more than one way to get to the Net, and nearly 7 million people have found it. According to IntelliQuest Research's Worldwide Internet/Online Tracking Service (WWITS), more than 83 million adults are online today. Of these, 3.7 million are using handheld computers, and 3.1 million use TV set-top boxes to get there. The numbers may be small now, but they're certain to grow: nearly half of alternate routers have been on the Web since 1995. The handheld crowd stays online longer and does more shopping there. Familiarity with technology breeds contempt, it seems, for standard methods.
