I have an ancient iPad 3 that is slow as molasses after the last software update they put on it, but it's still functionally the same as a new iPad "Pro" a family member has. I struggle to see how an iPad Pro is "pro" at any capacity, with or without iOS 11. An iPad "Pro" is still an iPad. Maybe for professional artists if they buy the optional $100 stylus?
