The phone specification is similar to the original ZTE Blade [1] also known as the Orange San Francisco. This originally went on sale nearly 2.5 years ago with Android 2.1 and by today's standards is considered low end.

If Firefox OS provides as good or better user experience than Android 2.1 on such modest hardware, Mozilla have every chance to carve out a market in low end smartphones.

It isn't right now, the interface is fine but the apps are really slow. The second problem is, the apps are written for the web, for example you often don't know where you are without an url.

Native apps, especially the popular ones are decent on a device like this. They were written for small screens and have a usage flow that is perfect for that form factor.

I remember seeing a demo of Firefox OS running really smoothly on a phone which was even lower spec than this one. It made me realise the reason why mobile web apps are slow is bad browsers.

I'm sorry, downvoted by mistake.

Blade had arm6 and no neon, so this is a big step up for CPU, which was the Blade's weakest area.
