I have an X-100 and love it, but not for anything that moves. The auto-focus just cant keep up. For museums, landscapes and such, it really is a great little camera, and I love the style of it, and I will be bringing it along as well.
For spur of the moment quick shots and stuff though, I just don't have the menus down enough and it frustrates the heck out of me sometimes, whereas I can grab any of my canon bodies and use them without thinking.
Since I'm not flying and not dealing with TSA, and will have my own car coming back, I don't mind lugging the heavier gear. I like to be prepared for anything.
