Free apps are found in the app store--there's a convenient button on the touch.
For those of you that have touches for the younger kids--Didn't you have concerns about their free access to the internet where you couldn't watch them? I feel like such a mean mommy. Our main computer is still in my living room where I can keep an eye on their web surfing, and my DD16 just finally got her touch that she's been begging for for a couple of years. She had a nano--which, by the way, I wouldn't hesitate to get for a younger child--but I was nervous about allowing internet access that I couldn't monitor. I know that there are parental controls, but I also know that the kids are more savvy than I am, and I feared they'd get around the controls. Guess I'm just not trusting enough.
