Kids voting on mobile tech
It's a Dust or Magic tradition to use a laser pointer to vote. That way, after a product is demo'ed, you can say whether you like it or not, and whether or not you think it'll be successful, and still stay anonymous. In this picture, these kids are voting on which mobile device they'd most like to play with.
Looks like the iPhone has 2 votes, PSP Go has 1, Nintendo DSi XL has 2, PSP has 1, Nintendo DS has 0, and the iPad has 3. The netbook, partially in view in the foreground, has 0.
In the DS' defense, it might have zero votes because it's sold 130 million consoles worldwide. Chances are, they already have one at home.
