It is very difficult to receiving incoming Skype calls and Google+ Hangouts when wifi is off wink

(for a while the N7 was the only Google+ client I could rely on to work for Hangouts, not an issue anymore*, another reason it doesn't get used)

* at the time Google+ Hangouts tended to hang Chrome on OSX when I tried and the iOS client didn't work very well for me either, both of those issues aren't a problem anymore
