That's nice, and I like the X100 for many of the reasons you provide here, but the x1 pro is larger, heavier and the hybrid viewfinder will only function on a few of the lenses. Again negating many of the benefits of mirrorless technology.I have used because I have an X100.No haven't used used it, nor has anyone else here. Many who have used the hybrid viewfinder on the x100 have reported mixed feelings. Its clear however that as a purely evf it is not as good as the nex viewfinder. However, its important for people to know that the "hybrid" part of the viewfinder is only available on two (maybe 3) lenses.
And although that camera is not a Pentax DSLR, it's everything else I wanted to experience in a camera. No new system (just a fixed lens), silent, small and ultra-discrete.
OVF is its stellar part, and the ability to control the camera without removing your sight through the OVF is what enhances one's photography taking experience enormously. Also the ability to nail the exposure PERFECTLY every time.
OVF is also brighter and overall better to my eyes than Pentax's pentaprism (K7).
And is almost half the weight of a K7+any lens combo (even DA40).
Image quality is stupendous.

My point is that while mirrorless cameras are great (I own one) they still do not replace DSLR' for many uses. The x1 pro crosses over some DSLR's (the K5 in particular) in its size dimensions making me ask the question; what am I gaining by going mirrorless via the x1? From what I have seen thus far from the specs there is nothing it does better and has some significant limitations to boot.
I would get an X100 because its smaller, simpler and more discreet, but it would not replace the flexibility and performance of my K5. The X1 doesn't even perform the role the X100 would for me.
I'm not knocking the X1 (just like I would not dare knock Leica rangefinder bodies) but they are not replacements for DSLR's.
