Spent a couple of days playing with this and I really like it. I'm enjoying the nice, clean IDE UI.

Haven't really built anything beyond simple test apps, but from what I've seen it could be a really great tool.

I recently came across Coordino (http://coordino.com/). I haven't tried it out myself, but it looks pretty polished.

It's also Open Source.

The title is a little misleading. Surely it should read Using only CoffeeScript, Titanium, Node, Socket.io and a Chrome extension...

In fact, the title has very little to do with the actual article (which to be fair uses the same misleading title). Should be "Building a Chrome To Mobile extension using JavaScript only".

It's a shame because the actual project looks cool, just wish some more details were included.

Yeah, definitely a little worrying. I'd love to hear about people's experience as we're considering working on some apps specifically for WP7.
