The CCC previously published a German minister's fingerprint. They acquired it by lifting a water glass he had used at a public event. http://www.edri.org/edrig

  This doesn't really translate to an everyday attack vector. They had to have served the minister a drink that would not cause precipitation to form on the surface of the glass and specifically target him. Then you need to actually process the print. A better measure would be how easy it is to lift a usable print from a crime scene. But even this has problems. You need to target a person to know whose prints you have. If you just randomly pick pocket a phone. How do you get the print? How do you identify which finger was used? You need to get lucky or get 10 good prints. I agree with others. The real question here is, "Is this better than no password?" I think the answer is, yes.
