I thought of that too, but I had the X100 and the X100s and although they were pretty boys I didn't really gel with them and I don't know why. I bought a used XE2 in the Summer and saw the dreaded smearing in the foliage and it put me off it straight away so I'm considering going back to the XE1 and 35mm. Same sensor as the X Pro 1 I think .....
Yep, I experienced the same ( and bought your X100). The XPro 1 was 'the' camera of all the X series for me.. But, that sensor is not going to see light of day again (i read that the smearing is here to stay) so I reckon its a case of getting to grips with it or finding another platform. Yet, i still hanker after the X system. Sigh.....
I finally made up my mind, going back to the XE1 with the 18-55 kit lens and 35mm 1.4. I much preferred it over the X Pro 1 for usability. It comes with an offer for a free tele lens that I doubt I will use so may be able to get a few pounds back on resale.
