It's hard to keep driving, walking the dog, doing the laundry or dishes, taking out the trash, typing your report, etc. while staring at a camera and someone else's face on the screen, but it's pretty easy to carry on a voice conversation with a hands free bluetooth headset.
Call me Captain Obvious, but I still buy a phone to make phone calls. The only time I would want the front facing camera is if I was overseas and wanted to voice chat with the kiddos.
OH CRAP! Berizon doesn't have very many phones that have a front facing camera that are also world-ready, do they?? Do they even have one?
Anyways. I agree. They are nice on laptops and tablets, but less useful on phones with such small screens. Increasing tendency to further cap data plans is only going to make FFC's on phones LESS attractive. I suppose they make a cool mirror ...
