Meta, question for 720kb.

I'm on mobile and wanted to zoom but you've used this in the demo page:

    meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"

I'm curious why? The hit targets were too small for me initially, hence the desire to zoom.

On topic: I like them, used sparingly or in the right context I think they'd be very good. Thanks for sharing.
