For the first time ever, toddlers (as in, people too young to understand how a Gameboy works) are interacting and playing in increasingly complex ways. It's not a niche often covered in HN, but the childrens' app market is booming at an unparalleled level: it's why everyone from Amazon to Valve is trying to get involved, because suddenly we have this ubiquitous magical technology that lets our five year olds learn fractions while being on an adventure -- and the price is $.99, instead of an overpriced $15.99 pop-up book or a $49.99 DVD.
There's a lot of FUD in this overwhelmingly technological age, but I think it speaks volumes when I think that I'd rather be a kid now than any other time. The future is bright.
