Review on WinJS by Devon Holmes

I like the fact that its so easy to build applications using it and its free! Its extremely fast, even on older browsers. It's very easy to get started with. Nothing really at this point but if your looking for something to help you build quick prototypes of mobile applications then this might be what you're looking for. The only downside is that it does not have a good API to interact with native OS services. If you want to make games and apps I would highly recommend trying this out. We are building a game where our players need to navigate through different levels and solving puzzles. This has been a huge time saver over other tools we've used in the past.
