As long as the firmware is not buggy for him, the Chinese brothers pile.
Well, about the Chinese firmware, I myself use a shell from the Middle Kingdom (MIUI) and IMHO of course, but this is the most convenient, and really intuitive shell!
Yes, and the software in it is really good, one backup is what it costs (backup of everything, starting from the icons and folders on the desktop, ending with all the software, and accounts / contacts / passwords)! + The only thing the default audio player could not handle was the disk image + .cue.
An acquaintance, clacked Miezu, also a shell, very nice (much better than a tachvis).
