A few weeks back I got a preview of a product that was incredible, and I'm happy to see that a public preview was launched last night. Adobe Shadow is a tool that lets you preview and inspect web sites on multiple mobile devices at once. You can use your desktop to drive the web browser on your iOS and Android devices. That by itself would be useful. But you can then also use a Chrome Dev Tools like inspection and editing feature to tweak the DOM of individual devices. None of this probably sounds nearly as cool as it looks, so take a look at the short video below:

You can download (and discuss) this new tool on the Adobe Labs site. You can also follow Adobe Shadow on Twitter and Facebook.
