The scary part of that trend is that biometrics should not be replacing passwords. User ID, fine, but finger prints are something you have, not something you know.
Even for id's, we need to be careful. They can't be the end-all solution, because they aren't permanent (I know people who have accidentally lost their thumbprints through burning, for instance). Phones today get around that by making you also set a pattern or pin to get in.
