Skype 2.8 UI was messy, with windows popping up everywhere and sidebars going crazy.
Skype 5 is just perfect, and in all honesty can't find anything wrong with it a part of the chat while calling thing.
Agreed. I have no idea why the author prefers the 20 window view http://cl.ly/5cqD to Skype 5 http://cl.ly/5cmT I've hated Skype's UI until now. Personally, I think everyone's greatly mistaken for thinking otherwise.
I prefer it because I don't have to click five times to see everything I need to see, every time I haven't looked at Skype for half an hour. And I prefer it because I don't have to constantly switch between chats just to see what people are writing. I apologize for being mistaken in this, of course :-)
