With the mobile war between Apple's iOS, Google's Android and Microsoft's Windows. The arrival of Ubuntu will be something. We all knew the king of the open source in mobile as of now is the Android, with Ubuntu coming over, will the developers turn their coats? Will Android lose their fair share of the "masses" or will iOS and Windows finally dominate the mobile market as they dominated the desktop?
By the way, Ubuntu is not just making their new OS, they are making their own phones as well, so expect a fierce competition in hardware.
