As a new fellow new dad, I saw this and thought "that is very impressive technology", but as a learning instrument and toy, why is the iPad required? The iPad seems like a replacement for the parent. Instead of an iPad I can sit sown with a kid and say, what letters do we need to spell fruit, and I can sit and help her find them. Or what shapes can we make with these blocks, or can you help dad make a cat? The technology in here seems to be an attempt at automating the parenting, so instead of me sitting down with my daughter I leave her in a room alone with the iPad (as seen in the video) and go do something else.
