Parents - What are your thoughts on the iPhone / iPad as an educational tool?
I am hoping to get a feel for how other parents are using the iPhone/iPad as an educational tool for their kid(s). It seems like there are a ton of options to keep track of: edu games in the Apple App Store, eBooks, videos on the web like Khan Academy, etc.
If you use anything like this, is it a pain to find the good stuff? How do you knows what works?
