Node - for node-webkit, I believe. As for the general question - why use web technologies for desktop app, I think it's like "Qt for those who don't want to use C++". Cross-platform GUI toolkit. As someone who used Qt extensively in the past I don't see a lot of value in using web technologies to develop desktop apps, unless there's a plan to use the same codebase on the real web. But it's just me.

I'm currently building a desktop application for work, and this is the reason we've got with node-webkit -- we are using the same code-base for a client side web application with slightly different uses. Being able to do so is quite a boon, to be honest, and is cutting down dev time dramatically.
