              Snapsort, (or anyone)

              I'm a college student/graphic design, and I travel a lot. I really love the lightweight, small body of the mirrorless cameras and really don't see a big set back for me in terms of getting the sony. My main requirements are decent videos, ability to take multiple photos at once, easy to switch out lens b/c I have limited knowledge of camera (though I do have some, it's mostly with fil cameras), and overall great image quality. My budget is 400-800, and everything on snapsort points to the Nikon 5100--which I would definitely get over the 3100 because of the need for video, but I'm wondering, given my needs, if a smaller, easy to travel with camera would be smarter. I'm looking at the Sony and the Fuji X10 when it comes out. 

              Feedback? Opinions? Anything!
