> "FireFox OS has less processing and memory requirements, since the OS and the services live mostly in the cloud. For example, most of the apps written for Firefox OS are written in HTML5 and can be run within a mobile browser."

But then if you need to do very heavy computation, like photo editing, wouldn't that require good GPU? Can $25 provide that? Also consider running multiple webpages (try open tumblr on mobile) and multiple apps in the background. I haven't never owned FxOS but I honestly think this statement is for bare minimum flip-phone. If people have negative reviews for the one in the market (ZTE Open, for example), how could a $25 beat the $79 one?
