I have the Pro. Have owned it since launch and one thing I will say is it's fricking HUGE, don't let yourself be caught off guard. I suggest a lot interested parties go to your nearest Best Buy or Apple Store and play around with a demo just to get a sense of its gargantuan size...
After that, it's a very fast and capable device and, depending on your specific needs, can act as a primary PC replacement. This is where it gets murky. For myself, everything I do is mostly centers around the Internet, email, and for work Microsoft Office and PowerPoint. The iPad pro can take care of 90% of my needs, the only reason I still need my MacBook Pro is for music and media storage.
