We used a device called an "iclicker" at my school that could do all of this, though it was pretty much only used for paperless pop quizzes.

One benefit was immediately after, the teacher could display a bar chart showing the correct multiple choice answer and how many students voted for each of A,B,C,D thereby giving students and idea of where they ranked in the class.

How is that a benefit? Won't that just promote feelings of smugness or worry? Surely a students independent learning is what's important, not where they rank in an arbitrary group of others? Did they really emphasise this aspect of it?
