I wrote about the first Firefox OS phone a while ago, but now you get the chance to see it in action thanks to the ZTE Open, a phone produced in China. The device is a entry-level smartphone powered by a 1Ghz processor, and features 256 MB of RAM, 512 internal storage, 3.5inch display, 3.2M FF Camera and a battery of 1200mAH. The specifications are not that great compared to other smartphones on the market, but we get to see the Firefox OS in action. The new operating system from Firefox is built on HTML5, so apps can be run directly from the internet. No app store is needed. Pretty cool, right?
