The Kitkat update worked without problems. After that I had, however, the problem that was not good to hear in discussions of the caller. Within 2 weeks there was already a fix for it. Here ran the update without problems and after that everything was working normally again. Otherwise, I think the Moto G a successful smartphone. It runs very fast and stable. Had been no crashes or errors (except for the above-described). The boot process also does not take all too long, if you do it once completely. In my opinion, it might be a bit narrower (or smaller overall), then it would be better in the hand.
