congrats on the new x-e1. the 18-55 lens is an impressive piece of glass. you'll have a lot of fun with that camera.
so far my biggest disappointment is that it came at the beginning of my 3 day work week. so i haven't had any time to play.
the handful of raw files i took on Wednesday wouldn't load in lightroom, but i found a beta acr release and that worked fine, the image quality is truly impressive, it seemed better than my x-pro or xe-1, but i haven't taken enough shots to really judge that yet. the viewfinder is the best I've ever seen, bug and bright. love the manual focus aids, esp. the split screen focusing.
the camera controls are all in intuitive spots and build upon the previous designs of other x series cameras. the programmable buttons are a nice touch without being too confusing about what their assigned functions are.
