Lot's of good discussion here. I teach computer science (Full Time) at the college level and am also an equipment addict. I have six laptops, several servers, multiple android phones (I use an Android phone as does my teenage child and I use them as devices such as a dedicated engine control monitor in my truck). I also have multiple iPads (old ipad 2, ipad air, and ipad air 2) as well as four Android tablets, and even a chrome book. I even have devices such as pogo plug's which I've hacked into low cost Linux servers. Of *ALL* of these devices, my son uses the iPad more than any other device, including his phone. As far as I go, I spend more time on (one or more) laptop's, but also think the iPad is fundamentally easier to use and less effort to keep updated and working efficiently than the Android tablets.
FWIW.
