From what reviews say, the Apple Pencil is pretty much the best stylus for drawing out there. So yes, if you make your money exclusively in art/graphic design, this is more a 'Pro' tablet than anything else out there. But it is a niche market, and much like a lot of Apple's stuff, it does one thing very well rather than trying to do everything and excelling in nothing (which IMO is the right attitude). This isn't meant to be for the masses.
This seemingly recent trend of people saying that it's not a Pro tablet because it doesn't run OS X software is ludicrous. And people wanting OS X on a touchscreen is even more bizzare to me. Heck, Apple never even marketed this as an alternative to the Surface Pro. If you start comparing them, you're missing the point.
If you have a need for the iPad Pro, there's no other tablet that does what it does, as well as it does. If you're questioning why anybody would need an iPad Pro, then you quite obviously don't need one. Get a Surface Pro or a MacBook instead.
