We happened to win a Kindle Fire HDX tablet at an event. Since we've been talking about getting the kids a tablet for a while I thought "yay, sorted"... until they actually tried it.

There are no apps for the thing. Or, rather, the apps the kids actually use, YouTube, various games, Google Maps, etc, are all missing. It's also rather insistent that I bind a credit card to the account... um, no, it's a tablet that kids will be messing about with. Sideloading to try to get Google Play to work so far has failed (it installs and runs, but can't actually view any selections). It's also, AFAICT not yet root-able, so there's no easy way to get an alternate build on it.
