For me it doesn’t have anything to do with thinking the OS or apps aren’t professional grade. For me it’s the fact that there is a big literal and potential difference between the 9.7 iPad and 12.9 iPad and it seems in a lot of discussions or articles people can’t be bothered to tell you which they are talking about or if that is even a factor, just “Pro”. I’d even go as far as suggesting that this lack of name distinction has even made Apple apathetic about making any meaningful difference between the two. With so much news on “Pro” that could be talking about either or both, nobody is really calling them to task. A stellar review for the 9.7 could be seen as the same for 12.9 because the author didn’t even bother mentioning it.
