Earlier quoted context omitted.
Maybe it's an American thing but I don't think I know a single person who owns or uses an ipad, with the exception of rich parents who use them exclusively to distract children. I certainly don't notice a lot of ipad users in airports or trains.
I’m in the UK. Yesterday I watched an eighty-plus year old woman settle her similarly elderly, physically-impaired husband into his seat on the train then get out her iPad to write an email. On my journey home in a more crowded train I saw half a dozen iPads just from where I was sitting. They are extremely useful devices for train journeys.
Similar to the parent I only ever see iPads in two places, the hands of rich kids in restaurants, and in primary schools.
