Fujifilm appears to have incorporated a lot of the X100 feedback in the X-Pro1's design and it is great that they did this. There are numerous improvements the bottom line is that you are getting DSLR image quality in a compact, functional body with high quality optics. Current X100 owners will feel right at home and it should not take too much time for a new user to become familiar with the X-Pro1.
The build quality is excellent, just like the X100.
Fujifilm have done a great job with this system and I look forward to it expanding over time.
I like the X-Pro1 so much that I have just pre-ordered the body and all 3 lenses. I am confident enough in the camera to use it for paid client work.
