An interesting question. Is the iPad a computer?
Your average power-user (let's say programmers, Apple fanbois, Android users, and me) would say, "Umm hello? Obviously!" But your legions of average regular iPad users (grandmas, and your average college students) might not agree. But if you asked them what an iPad was, if it was a computer, they couldn't quite be able to tell you. "Umm, yes? But wait, it can't do so many other things."
This means, as a society, Apple has forced us to rethink the question: "What is a computer?" and "Is the iPad a computer by this definition?"
