The system is still extremely buggy. It closes in mid-writing-a-text message or mid-call. You expect this behaviour from a toy, but not a phone. Mind you, to people in emerging markets, it is a tool, not a toy, even if they only pay $25 for it. To these people, it's a lot of money. The hardware is very slow. It is too slow to render HTML5, which is especially hard when you have to type on the touch screen. The problem is that the system lags quite long after you touch the screen, so you are a few letters ahead of what is on the screen. There is no feedback. So, to me, Mozilla is really disconnected from reality if they think this could work.

I love what Mozilla is doing and I'm tempted to move everything possible to Mozilla. I love the idea of ruthlessly developing for low end systems rather than just assuming everyone has 1 GHz and 1GB. I hope designers and coders enjoy the challenge of working with such limited systems. I tried to use Paypal website on an iPhone 4 yesterday. It was painfully slow. It was loading a bunch o stuff that I just didn't need or want. Horrible experience.

  I dream of having an iPhone 4. I guess it's subjective what you call slow.

    No, that's the point. This ridiculously overpowered phone was cripppled by PayPal's website. The phone slowed to a crawl. The website was loading odd stuff and doing weird things.

  Your attitude seems contradictory to me. Firefox OS is very, very heavily focused on the use of HTML5, JavaScript, and other web technologies for the development of mobile applications. Yet as you found out recently, apps or websites built using these technologies are often extremely inefficient, even when highly tuned by very experienced developers. To get good performance on limited devices, the best thing to do is to move away from HTML5, JavaScript, and related technologies. Applications written in C, C++, Objective-C and even Java vastly outperform HTML5/JavaScript-based apps, especially on devices with limited capabilities. Yet this is completely contrary to what Mozilla is doing with Firefox OS. So it seems really unusual to me to support them and their efforts, when it's clear that their approach flies totally in the face of what you'd like to see happen.

Citation when it comes to Java (assuming you're talking about Dalvik, because that's the relevant Java implementation on mobile)? Dalvik is not generally considered as fast as either V8 or SpiderMonkey.

      Unrealistic micro-benchmarks aside, I've yet to find an Android app written using HTML5 and JavaScript that feels anywhere near as smooth and efficient as native apps written in Java. I suppose I don't have numbers to back me up, but I'm not sure that really even matters. The performance difference is something that users notice.

        Those companies have an agenda to sell regarding HTML5 development, plus as soon as your target middle to low end handsets it is turtle speed time.

        Those companies have an agenda to sell regarding HTML5 development They do. However, don't be so quick to dismiss the point they are making: on high-end devices at least, html5 apps are at least as good/performant as native apps. By the way, Apple, Google and Microsoft each have an agenda as well: to enclose developers in their walled garden, making them learn and use proprietary non-cross-platform APIs so that apps can't achieve a "ship new features everywhere, at the same time, easily" approach. They also want you as a user and a developer to abandon your phone after a while by deprecating APIs and making the OS effectively non-updatable, and making it very hard to update manually (do you know how to port Cyanogenmod to your device? Fix its bugs?). as soon as your target middle to low end handsets it is turtle speed time. ... on Android. It probably isn't great on low-end or old hardware (although light pages should still run fine). However, Firefox OS is designed and optimized for running those webapps on low-end hardware, contrary to Android. Which vendor do you trust to make the web fast? The ones who have nothing to gain from it, because they wouldn't be able to retain users anymore who could switch to a new OS in a heartbeat if all the apps were webapps? Or the vendor who made huge contributions to the open web?

  like Paypal website will work better on a 25$ handset running on javascript, Are Mozilla fans that dishonest, just because it's Mozilla ? What kind of person are you?
