It's the same view with using iPads/tablets as a home cinema controller. Folk love the idea of yet another use for their precious tablet. What is often forgotten is that the phone or tablet is a communication device for their social media too. In some cases you have calls/texts/emails nagging away as well. There's a constant sense of distraction with these, so it's a bit of a double-edged sword.
I'm not on any social media myself so I don't really get that nag. I understand others may of course.
