Android isn't just for nerds. In fact, it's not even only for adults anymore. If you have kids, chances are they're constantly demanding time with your phone or tablet. But even that's just the start. Sure, it's fine to use those things as babysitters (OK, maybe not fine, depending on who you ask, but we're not here to judge), but phones and tablets really are just a drop in the bucket today when it comes to kids and Android.
These days it's just as easy to fire up a movie or music on Chromecast, using your phone or tablet to control it. Or maybe your kids prefer one of the newer Android-base set-top boxes, such as the Amazon Fire TV, or the new Android TV.
Point is, it's almost impossible to keep your kids away from Android. So don't fight it. Teach them. Help them learn. And help them enjoy it.
