I’ve had to use it for a week now. It has the most braindead, unintuitive UI I’ve ever seen. Unbelievably inefficient. So much wasted space. Parts that don’t make any sense at all. Notifications are a crap shoot. It crashes during conferences and blows through memory like mad. Whoever signed off on this trash is certifiably insane. Skype was uglyish and clunky but at least it worked.
