Talked to my sister in Spain for 45 minutes the other day...saved some nice $!

Usually about 2 hours a week spread over 3-4 calls, all overseas. No more calling cards.
 
I never use Facetime, its useless because it's not available on other phones. I use Tango to video chat my girlfriend though when I'm out of town though usually 30 minutes to an hour long every night.
 
Been there, done that, useless feature.

So much nicer to do on the MBP with it's larger display. I know a lot of people of all ages with iP4's. Face time fails to impress.

I only know one person who uses it and he's as narcissistic as Jobs. :)
 
My lil cousins FT me once every other day. I just go and hand it to my little sister. When I do FT normal friends though its about a few minutes to half an hour.
 
My girlfriend and I both have iphone 4's, and even with both of us wearing earphones, we have found that with the standard voice channel, it's sometimes hard to understand each other, so we end up turning on facetime, and just using it to audio chat. On average 1 hour conversations or so, few times a week.
