What Mozilla is doing with Asm.js and Firefox OS is nothing short of impressive. Web apps that can be downloaded from anywhere, and cached offline with full access to native APIs? This is the democratization of app programming at its finest, especially since JS has become a 'platform', and now even has a bytecode target (asm.js).

Not to mention, offering unlocked phones at such low prices, with potential feature parity (at least when the app ecosystem gets better) to iOS and Android is huge. I would personally love to never sign another long-term contract...
