Video calling has a place for things like calling distant relatives & friends you rarely see, calling your family when you're travelling etc.. but for everyday calls, no thanks. I don't need to see the person and most of the time don't want to be seen when I'm on the phone.
One time my friend said he was gonna Facetime call me at a certain time so we could try it on our new iPhones. When the call was coming, I had to be sure to be dressed properly, checked the mirror to make sure I didn't look like I just escaped from prison, and I looked in the mirror and said "WTF am I doing ? I'm getting ready for a freakin phone call!?" And that was the nail in the coffin for "casual" video calls for me.
