The iPad Pro is designed as a competitor for the Surface. In case you missed the keynote, there was a large proportion of the time taken up by Microsoft and Adobe demonstrations showing how iPad Pro can be used in a business environment.
As a productivity device, iPad Pro will probably fail. I missed the announcement that it now works properly (i.e. supports screen/application sharing) with business tools like WebEx and Lync. I can't dock it and use a multiple monitor setup. And that's just the tip of the iceberg.
If I was looking for a consumer device, the sure. I'd probably choose an iPad for consumption. But for business use, it is nowhere near being a serious competitor for the Surface Pro.
