It's viable for me. I'm at a friend's house and need to type my password into their computer? Never going to happen: they're likely not very good at securing their computer, and there's not a chance I'm going to risk compromising my password because I can't wait until I get home. Besides: I have a smartphone with Chrome, I can use that. I need all of my passwords with me? LastPass.
