I like what I see of the Q, and would likely own one.....but a viewfinder is a must have for my needs. From what you say here, I would go with the Fuji X10, I shot with one for over a year before I got my new X20, and I can tell you the X10 was a delight to use and performed far beyond my expectations. No lenses to change, easy to use.....if you just set it in EXR mode you can shoot forever and most always be pleased with the results....build quality of the body is second to none, metal and rock solid, and the Fuji colors are wonderful.
At their current price, the X10 is a steal, and I can't imagine you not falling in love with it for your intended purpose, as so many others have done.
Here is a years worth of misc X10 shots, the good, bad, and ugly all mixed in. Did I mention, this is a fun camera to use, more fun than you can imagine without actually using it!
