It's definitely true in our house. I've been showing my son websites, apps and videos with ours since he was about 4 months old. He's now taken it over, for the most part. In fact, he cries when I take it away, poor little guy.

The thing I find most frustrating, however, is the usability. It's not just that my son gets confused when switching from an interactive app to a video (thinking he can interact with the video the same way he does with the app, he's 9 months old afterall.) It's that the apps themselves have such poor usability. Especially children's apps. I love Elmo's Monster Maker from Sesame Street, for instance. But the navigation has hidden functionality and choices that you have to cycle through accidentally before you discover them. It's  like mystery meat all over again. Don't mean to just pick on them, because it's one of our favorites. There are also so many apps that don't lock away navigation while a game is in play and my kid accidentally changes screens and get continually frustrated.

There are a lot of really fun things about Apple's intuitive interfaces, but designers need to catch up with usability, particularly if Adobe's going to turn millions of them lose on the interactive world.
