i'd love a third player to enter the hardware space. i've been wanting this for a long while. each attempt has failed as the software sucks or the hardware is mediocre. no one wants to completely gimp their mobile experience just to say that they're using open source hardware/software/whatever.
the new player would have to be large enough to withstand several years of losing money and no profits though as people won't switch overnight and it will take several years for the hardware and software to mature to a point where people would be comfortable to switch.
