XPRO1 and DSLR are different type of systems. Those who get used to DSLR will find that XPRO1 AF is slower. But once you get used to the XPRO AF speed, that should not be an issue for you anymore.

Starting I felt the same with you too, but when use for a period of time, I began to love XPRO1 more. The image quality and colours are SUPERB!
Like ahpan said, do not compare the XPRO1 with a DSLR because they are simply two different systems. There will be times and situations where a DSLR is the best choice, and other times where the XPRO1 is preferred. I own both systems and choose my gear according to my needs.
By the way, every camera system have their strengths and limitations. Most people know what a DSLR system can offer. It is not necessary to benchmark all other systems to what the DSLR can do. If you must have everything perform the same as DSLR, then why bother to try other systems? Might as well just stay with the DSLR!
I shoot DSLRs (Nikon D3s and D700 with a collection of prime and zoom lenses). I also shoot XPRO1 with the 3 primes (18, 35, 60). I still shoot film (Zeiss Ikon ZI, Hasselblad medium format film, and the very special Hasselblad XPAN panaromic film camera).
The joy of photography is to be able to try out different systems, experiment, explore, be creative, yet work within the strengths and limitations of each camera system.
Enjoy the journey and share knowledge and experience with others.
Nowadays, when I don't want to carry the heavy DSLR system for travelling, I bring along 2 XPR01 bodies each mounted with a different lens so as to be able to capture moments as they happen. And I don't have issues with the AF because I work within the limitations of the system.
Cheers.
