>programmers could write an app just once with Web technologies that span not just iOS, Android, and Firefox OS, but also Windows Phone, BlackBerry OS, Tizen, Ubuntu and any other mobile operating system that arrives tomorrow.

This, to me, is the most powerful prospect of Firefox OS.

I have been "writing apps" in HTML, Javascript and PHP ever since I can remember.

They are just as responsive and useful as any app I have ever used on my Android. Which works fine, but had recently been creeping the heck out of me because it's distributed by Google.

Every app is virtually a simple website imho. Look at google docs, for example. Angry birds could easily be written in javascript. As could flappy bird, and virtually every game I can think of.

I see no reason to bother writing a piece of software that can only be used on Androir or iOS, except for sheer greed, so I haven't. It's worked out well for me so far.

Here's to hoping Firefox OS comes to the first world sooner rather than later.
