Updating

Updating took FOREVER! It took me about 3 days to get through the iPads. The problem wasn't the operating system update, it was the app updates. Pages took at least 15 minutes. I started with all of them plugged in to my Macbook in the cart, but didn't want to sit there all day long since it seemed to be updating them one at a time. I decided to pull 5-10 iPads at a time and just lay them out in front of me instead. I am confident that there is a better way to do this, I'm just not sure what it is.
