The facebook phone revealed a pleasant surprise and that is that other than the facebook home which can be disabled right in the apps menu, it runs 100% vanilla android. Even the stock android launcher is preloaded. This makes it the first aosp htc device since the g2 and the nexus one. Its also got the lcd2 screen like the one x, and is a relatively smaller device for those looking for something 4.3 inches. This also means that roms like cm10 and other aosp roms should be 100% function since this phone uses the stock android framework and not the butchered sense version that makes porting aosp roms a major pain.
