That's the personality issue I was referring to. I can see the infomercial now... "Is asking the person you share sleeping quarters with for the $5 he owes you causing hernias and cold sweats? Is retrieving a $10 bill and handing it to a person you see during most of your waking hours just too much damn work? Do you think checks are for old people? Then listen up, 'cause we have the product for you!"

Snark aside, I'm probably just being short sighted. People said the same thing about early consumer digital cameras, too (1/16 the resolution of film, 5x more expensive, mega slow, one lens, and 5 pictures fills up my hard drive? Where do I sign up?!) and now it's ubiquitous.
