In addition to the companies presenting today, there's also the little guys who are wading through the crowd to find investors and customers.
James Wen left Amazon.com about two weeks ago to pay full attention to his new startup, Positive Motion.
His company puts the concept of flash cards used by students onto the mobile phone. That way users have the flash cards wherever they have their phone. When the class is over, and they no longer need the content, they can be uploaded to the company's Web site for sale. Wen's company takes a percentage of the profits.
The software also has quizzes and multiple choice questions, and as you learn the items and decide to knock them off, your confidence level goes up on a color-coded meter.
Does it require a high-end phone or 3G? Wen said no; he wants to make it as easy as possible so people will use it.
"I got this phone for free," Wen said. "I don't even know what that [3G] is."
