I'd say discovery is an issue. I'd like to be able to instantly find a product/service that hooks into whatever my kids just discovered. It won't be used for long probably, so it's more a matter of supporting micro-skill advancement than a complete course in whatever that's looking for long term users. For example, one of my kids got into Thomas the Tank Engine. I got her an iPhone game that taught here eye-hand coordination and puzzle solving. Lasted for a week, after which she got into toilet training. There's an app for that (Pepa Bath, pretty cool). You catch my drift...
