I am in the technology field for work so I have been into the tablet since before the first iPad came out in 2010. Few realize that PC manufacturers were making laptops years ago that could flip and around and turn into a tablet. The screen's were not capacitive (no multi-touch) and it was cumbersome and slow.
Since iPad I have been also using the increasingly popular Android devices and am quite satisfied. I'd say about 50-60% of my cong. uses tablets at the meetings. It's easier, less books to bring. Until the next big thing comes along tablets are here to stay. Use them..
