I like the idea of the iPad pro...but even as a huge Apple fanboy, I can see that it's not quite there yet...
I think that this debate is justified, but... over-done.
What makes the MacBook Pro different than the MacBook or MacBook Air?
-Better CPU? (yup, the Pro has a better processor)
-Better Graphics? (yup, the Pro has better graphics)
-Better Connectivity? (it has more ports. how many do you use?)
-Better Display? (on par with the MB)
-Better Battery? (MBA is the best by far)
-Different Materials? (on par with the MB)
-Thicker? (yup, the Pro is thicker)
-Heavier? (yup, the Pro is more heavy)
iPad Pro vs iPad Air 2

-Better Display? (on par with the other current iPads)
-Better Battery? (on par with the other current iPads)
-Different Materials? (on par with the other current iPads)
-Thicker? (yup, the Pro is thicker)
-Heavier? (yup, the Pro is more heavy)
Don't judge the hardware's "Pro-feel" based on what software is available to make use of the hardware.
