I think that a huge bunch of people have them because they are the latest thing in dildotronics, and its' a whole new way to amuse yourself to death. On the other hand, I'm sure an equally large number of people have them because the other option is unemployment. For many people the pace of business is now so fast that if you don't have that capacity in your pocket 24/7 then your no longer a part of that business. That might seem silly, but think - it's true for phone phase one (those land line deals), if you don't have a phone number most places won't hire you. Now, lots of gig-based jobs put calls out and if your not back to them in five minutes (or less), then they are on to the next person - that's the efficient way for them to run their business, and if you can't comply, then find a new line of work. Also, lots of people work in areas where documents and revisions are ubiquitous and constant, and you have to have the ability to receive (and send) on a moments notice. I imagine that most of that trends to urban setting, and to more advanced jobs - but soon come, everyone will have one.
