If you're a marketer or a media company thinking about mobile audiences, here's a little perspective. (See this report.) While there will be plenty of on-the-go laptops with broadband access in the US, they'll be dwarfed by the number of 3G mobile phones. Broadband phones will reach critical mass -- 15% to 20% of the population, 40 to 50 million users -- if not mass-market reach, by 2010.
