Unless your tied to Microsoft Products (including Skype for Business), its not worth buying the Surface Hub.

Care to elaborate? What doesn't work? Can't you use normal Skype?

Its been several months, but I recall it is really tied to Skype for Business (Lync), and having a windows domain. The office that had one of these didn't use skype for business nor had an Windows domain. It can be switched into a dumb display mode though, but performance in that mode is iffy.
