Zoom-in Online

The big demo during the Web section was around SuperPreview within Expression Web.
Key things SuperPreview does, brings up the page in a multi-browser comparison view, allowing you to see the same page in various browsers (Safari, Firefox, IE, etc) not only side by side, but in "onion skin" overlay mode, allowing you to see any differences between browsers.
Fantastic aspect of SuperPreview - it goes to the cloud to render in browsers that you may not even have on your machine. He showed examples of rendering in IE6 and Safari, using the cloud service to render in those browsers that are not installed locally.
For the first time you can see the page on, for example, IE6, IE7 and IE8, from the same machine - no more VM's, endless alt-tabbing, etc.
In my opinion, SuperPreview is a misnomer. It's really SuperWebDiff - gives you a set of incredibly powerful tools to diff the page across various browser renderings and then drill down and fix cross-browser rendering issues
