My only criticism is the lack of cable management. And hopefully for a future release they will add support for a Sony NPF battery since I only use it occasionally. So for me I'd rather have a battery than cable dangling all the time.
But since I knew it didn't support battery power when I bought it, I can hardly moan about it.
Hope that helps someone else who might be like I was, thinking "Meh...this will be rubbish"
