The iPad Air 2 is a very good tablet. I would question why the user wants a Pro, other than it being called "Pro"... like I said, it doesn't really offer features that are significantly better for the intended purpose.
Why do you need to question a persons choice? It is, after all, a personal choice and not yours to question at all. The OP asked a simple question which required an answer that others gave but you went off on your own agenda questioning rather than answering. No offence, but it annoys me when someone asks a question and then posters that don't know the answer have to go right off topic and dilute the real answers. JMHO?
