Most folks aren't using a mobile carriers conference call services, but rather are dialing
into an existing conference call service.
For a business user, it is an interesting idea. The corporate office is decentralizing with more users moving into unassigned workspaces or working from home entirely. I spend probably about 6+ hours a week in conference calls. Being able to mute/unmute easily rather then: c c c c c c (to clear the conf call access # that was typed in manually because AT&T conf call services render 'w' useless) option->down->down->down->mute, unmute, option->down->down->down->mute all day long. This is really fun while driving.
