Video chat options in general frustrate me to no end. Skype - at least on Linux - have steadily dropped in quality over the last few years (the old cynic in me wants to blame MS for no particular reason). Back in 2006-2007 I used Skype video chats daily with few issues between the UK and California. These days I have problems getting it to work reliably within London, and have given up on it to let my son talk to his grandmother in Norway.
So I tried Google Hangouts. It's marginally better. But it's still awful, and odds are about 50% that one or the other end of just fails to work (suddenly wants to reinstall the plugin, or just plain refuses to recognize the camera).
It's just incredible to me that a decade after I had reliable, working video chat, things appears to have gotten steadily worse, not better... I have 10 times the bandwidth - or more -, for example, both up and down.
