It's spacious, I don't get erroneous output, and most importantly, you get a uniform click no matter where on the trackpad your finger is.
In the hinged trackpads, it's a pain to click at the top - often you have to slide your finger down.
This is less of an issue if you're more of a keyboard only type - but for me it's one of the first things I notice when I use a windows laptop.
Other pros/cons I more or less agree on, but in my book this is a big one that is commonly left out.
