    Emm … let me think about it …. pay that much for this one or pay much less for better ones that are running Android and for which many more apps are available …. This is a tough one :)
    I’ve said it before and I’ll say it again, I think Firefox OS and Chrome OS are crap IMO. Javascript and other web technologies are way slower and more power hungry than even Dalvik, let alone native C++ apps. Also for now at least web apps don’t really match high end native apps in features and all that.

    I’m totally with you there Marius.

    The “web” as it stands today is a nice set of technology, very suited to forms and finite data layouts. Beyond that, it is extremely unsuitable to almost any other type of application, partially because the DOM by its very nature of being an event firing object hierarchy, each of which can trigger layout updates, partially because JavaScript is way too flexible and heavy to ever be performant. You can only optimize code that can dynamically re-wire itself so far.

    The “asm.js” solution is yet another hack in a series of hacks to use JavaScript as it was never intended to be used, and is essentially an admission that hand-written JavaScript can never be performant. Essentially asm.js needs to be utilized as a compile target from a higher level language, and is best used in conjunction with tooling. That is, for JavaScript to even approach acceptable performance, it needs to be compiled using optimization hints, and the compile step is heavy.

    JavaScript really has had its day. That’s not to say that the web will not endure. It will. I still use it every day for various lightweight tasks, but until JavaScript is replaced, and an application specific performant application stack is introduces that sits OUTSIDE the DOM, performance per watt for web based “applications” will be massively behind their native counterparts.

    Firefox OS, like most recent “linux” based mobile OS such as Ubuntu touch and Sailfish OS, just uses Android drivers.

    I’m not 100% sure about this buy there’s a chance that Sailfish doesn’t use the regular Android drivers at least on the current Jolla phone. It might if Jolla decides to run Sailfish on Android phones.
