Yeah I'm excited about it and it's getting me to finally take the step from traditional web app development (vps, php, etc.) to more easily scalable app development - and it's all open source, no vendor lock-in, and hopefully affordable pricing in the future.

Look forward to seeing more tutorials & code samples online and on their site. For example has anyone tried out meteor (w/node.js & mongodb) with it yet. Also, hopefully it will integrate with some of the browser-based IDEs out there like cloud9.
