Think Differently about Facetime and your college years

At about 1:20 in the iPhone4 video Scott Forstall imagines a Facetime call with his (future) college-age kids. Really?

Really?  It was cool when i could email my parents from my dorm room, and ok, I can see the appeal for being able to call them from the lawn where I'm studying.  But havging them video-call me?  Whenever they wanted? 

If there are iPhones in 2017, I'm guessing that most calls to college students after 10pm on weekends go straight to voicemail.
