When I attended 2012 summer convention session I saw them everywhere. JWs sitting in front of me and off to the side all had iPads. I notice that, like me, several were looking up scriptures in the NWT from their pad rather than in a Bible. Several gave their pads to their children to look at when they started getting restless.
I finally pulled out my own Droid and started catching up on my emails and sending text messages. No one even gave me a second look (in spite of the fact that I had no badge and wasn't wearing a tie).
I certainly hope that more JWs will spend time, especially while sitting in the cheap seats at stadiums and larger convention halls looking up ex-JW websites and watching JW themed videos on YouTube in order to stay awake...
