I've had a cell phone for a long time, but the average monthly usage between my wife and myself is under 100 minutes (and probably 60 of those are because of phoning into meetings when I'm working from home). Typically the phone is buried in my bag, or the ringer is off and I don't notice it, so I'm part of the shrinking minority, too. We are, however, considering an iPhone. We're taking an extended road trip soon (4+ weeks), and figure the ability to find a campground or coffee without searching out free wifi could be useful.
