> I see that as a hassle, not a feature.

I said this in another thread, but it really doesn't seem unreasonable to require your attention to unlock your phone, since it requires your attention in order to use it!

It really is the speed that will make or break this feature. If it's slow, forget it, if it's quicker than it takes you to move your thumb to the screen, then it probably won't matter to most people.
