I'm wary of these, because form elements tend to be very, very very veryvery platform-dependent, and users (like me!) develop expectations about how toggles (i.e., checkboxes) should behave on the platform they're using.<p>I know this isn't your intent, but when the behavior of something like this fails to match my expectations, it is extra irritating, because I feel the author thought having something pretty and iOS-looking was more important than it being usable for me. Either that, or else s/he decided that I'm too stupid to know what I like, and decided to shove an iOS form-control down my throat.<p>That being said, I must admit that these are visually gorgeous, and their behavior seems pretty excellent at first blush. (But again, I am unsure how I will feel once I start seeing them pop up and inevitably being <i>even slightly</i> misused in the wild. I also haven't tried them on my phone yet.)
