Tricky Windows Phone 8

So one nice touch I found is that alternative keyboard are separate downloads. Keeps a bit of the bloat from the device. After all, why do I need the Russian keyboard, complete with autocorrect dictionary if I will never type in Russian? Then a minute later I notice my phone saying "Update available". Downloading the keyboards count as a system update. Also, the phone does this weird data migration thing from a system update. But that tricked me as I thought an actual update was available.
