One small, but big thing for me with the X-Pro1 and the finder is the inbuilt -2 diopter. That happens to be my correction!
Though my eyesight has degraded over the years, I can't think of any camera I have ever picked up that did not require any correction whatsoever. With the XP, it felt like the camera was made just for me from the first time I picked it up. Sorta' like a great first date.
