To add some context to the title, this isn't a traditional IDE in the browser.
It's a kind of experimental touch-centric IDE with it's own semi-visual programming language (your not exactly dragging boxes around, but your not editing text either).
I only played with it for 2 minutes, but it's apparent that this is a "research" project. It's not meant as a replacement SDK for whatever is the de facto standard for Win8 apps.
DeFacto Standard is Visual Studio Express (free with basic info). Allows you to develop in any of the Windows 8 UI supported languages, including Javascript. About halfway done with my first game (a visual novel), and I could see where down the line being able to pick up my work wherever I am and whenever I have a few minutes could be very useful. Would love to setup an IDE pointing to Dropbox for assets etc. Of course I am hopeful that the Surface Pro will make this a little more possible as well.
