Yes, but it's purpose isn't to resize on the fly as you change your browser window. It's to have one set of HTML that reflows to your device correctly depending on the viewport width. I just checked it on an iPhone 4 and iPad (both portrait and landscape) in addition to a desktop, and it works astonishingly well across screens sized from 3.5" to 27". Are the media queries a little laggy? Sure. I'll tolerate that over having to hunt down a stupid "view full version"/"view mobile version" link (and I'm sure some optimizations can be done). I think this will set a new standard for the term "mobile-friendly"
