I have auto update turned off and set it to send notification only. The updates work well and quickly. There is one con though, as soon as an update is available and a notification appears, the UI freezes and will not allow any touch screen input other than the update icon to proceed with updating. This isn't working the way I expected. I figured setting the tablet to auto update would cause this situation, so I turned it off. The system forces me to run updates and blocks the UI for anything other than that no matter which setting I select. This wouldn't be too bad except some days I'll get several batches of updates and it shuts me down until they're done.
