Well, I do like the idea of picking out a photo that lets me poke my mother-in-law in the eye then draw a smilie face on myself each time I want to log on. (I kid, I kid, I actually like my mother-in-law). As was noted, there are so many users that have passwords that make me cringe and are so weak they might as well not use one, so ANY improvement will be welcome. I know that some people have concerns that someone could look over your shoulder and memorize log in gestures, but I don't see that as being much more of a risk than someone peeking at you type in your password. What I am curious about is whether this gesture based login will extend to applications, and if so, I think it is a step forward for tablet security.
