Interesting article - thanks.
I've used a Canon 30D for a number of years now but got a 'surprise' birthday present of a Sony NEX 5 in anticipation of a family vacation to Florida, i.e. the theme parks, with our grandkids. The benefits of the NEX as I found them were excellent image quality, excellent video capability (which is barely mentioned in the article) and a considerable saving in weight compared to carrying the Canon and a video camera as well, not to mention the sheer convenience of being able to switch from still to video at the touch of a button.
But as ever, YMMV!
