I find voice conversations over the phone pretty good while walking, using wireless headphones so my hands are free. I do this a lot and pretty much forget I'm walking, can do it for hours if a call or series of calls needs it. As a result, it's probably my main exercise, and I much prefer this over a phone conference or chat while stuck in a chair. Video doesn't fare so well when walking, I agree.
