The first thing I did after getting Windows 8/8.1 on my new laptop was to install StartIsBack and disable all the Metro/Modern UI stuff. I find it very annoying (especially in a non-touch environment).
I'm fine with Mozilla focusing on Firefox for Desktop and Android. I'm a big user of both.
Yeah. Firefox on desktop (Mac, Linux, Windows), Firefox for Android, and Firefox OS (for that mobile phone competition angle). No need for Firefox on Metro right now (hardly any users and the ones there are don't know what different browsers are anyway) or Firefox on iOS (since it would just be a UI skin over the gimped version of Mobile Safari thanks to Apple's anti-competitive rules).
