Not sure if this has been posted already, but...
Article said:Mozilla reckons the OS will be lighter and faster, but also says it will be more open than the open source OS, Android. Google has shown some hesitation in releasing source code for recent versions of Android.
Except, it also looks like Android with some iOS influences...

The interesting bit is that all the apps are to be written in HTML5. When I first heard about the OS, I thought "Yeah, right...people definitely want to develop for yet another platform. This will work, sure." But if it's all in HTML5, then maybe the barrier for development is actually lower, and that devs will get the benefit of some code/skill reuse.
Also, Mozilla doesn't really need to promote its own products like Google, which may mean less restrictions for carriers and smartphone manufacturers. They would be able to morph it to their needs.
Maybe the OS might gain some popularity?
