It's definitely clunky, ugly and bulky. I don't like it either.
That said, it's not exactly the end of the world to have to run one of these. If I felt like running crossfire, I'd rather just put the stupid dongle in the back of my case than sit around and b!tch about it.
I still don't get why ATI went with something like this, though? Why ATI? Why God? Whyyyy???
