I like the metro look. I don't have a problem with it and honestly it looks awesome. UIs are taking a step in the right direction.
Also Skype looks almost EXACTLY the same in set up terms, let's take this into part-by-part brown townysis.
Old Skype: Got 2 main fields. Left side is contacts/yourself, right side is who you're chatting with (and other stuff I guess).
New Skype: Prettier GUI, same 2 main fields. One difference would be you had these two buttons that appear to have gone missing. (What appears to be groups and add contact? I don't use skype so don't ask me)
You've still got your contacts and recent contacts on your side bar, chat looks almost the same. but a lot prettier.
I'd say this new update is completely an GUI update and looks fantastic to me.
