We first heard about Mozilla’s Boot to Gecko mobile OS, back in July 2011. The idea is that instead of booting in to a tradition Operating System interface and then accessing your apps, devices running Boot to Gecko (B2G) would boot directly in to Mozilla’s web engine, called Gecko (hence the name) and all the apps will be web apps. While this may not sound very interesting at first, it does have some advantages to it. Since you’ll be booting into, what essentially is a browser, the web apps automatically become your native apps. Also, Mozilla won’t have to start from scratch, since they already have a ton of developers making web apps for their browsers, so porting them to the mobile OS shouldn’t be an issue.
Boot to Gecko - Web apps are the future, even on mobile platforms
