There is massive iPad growth in the small business sector. If you walk into a restaurant these days, it's pretty common to see three or four iPads sitting on the counter. Seems like every service like Amazon Prime Now or GrubHub requires its own iPad.

Daycares are also big consumers of iPads that allow parents to see pictures of their kids at school.

Many small businesses are now using Square to accept payments, which requires an iPad at every cash register.

Technically, for all or most of these purposes, an Android tablet would work equally well. But people still think "iPad" when a tablet is required.
