"Boot to Gecko, or B2G, is an ambitious Mozilla project
initiated to build a complete, standalone operating system for the
open Web. Boot to Gecko's primary focus is for use on mobile and
tablet devices as an open source mobile operating system that
provides the infrastructure to build apps with Web APIs.
"While still in an early stage of development, Boot to Gecko
ultimately seeks to provide Web developers with the same
capabilities as those building for operating system-specific
stacks. As a result, B2G would provide mobile users all the power
of HTML5 to go along with device capabilities such as SMS and
Bluetooth support and a more extensive capability model for
interaction with the OS filesystem, as well as a way to tie the
'native HTML5 apps' together."
