What's most troubling is that it will most likely used for passive consumption, not unsupervised play. My kid is quite sharp, but she couldn't use the computer mouse before 3 and touch screens before 2 years of age. Assuming that this is normal, what could children < 2 possibly do with it except passively consume?
