I have loved our iPads. We have three iPad 2 devices and an iPad Mini in our household.
I'm having the same problem with *all* of these devices. My biggest problem with this isn't so much that there's a technical glitch, it's that Apple seems so carefree about problems affecting anything on their iOS platform. (I can't speak for anything else.)
How hard is it for one of the wealthiest corporations in the world (criticized for hoarding cash) to have status pages that are 24/7/365 and up-to-date? Others manage it! When iMessage goes down, you see it on The Verge, Next Web, Gizmodo, etc. But nothing where you can go straight to the source (Apple) and see the status on a "dashboard" like interface that shows where there are outages, a quick explanation, etc.
Here we are with this problem of updates not showing up ---- silence from Apple. Again.
It reeks of arrogance, entitilement, and the very old problem of simply taking their customers for granted.
