The Open Handset Alliance, led by Google, is developing and releasing the Android mobile OS.

But Android is not the only open mobile OS in town. Another noteworthy player is the LiMo foundation. Its mission is to produce an open, Linux based software platform for mobile devices. LiMo has been around longer and there are already LiMo devices in the market.

There are other efforts towards putting Linux on mobile devices:

• Motorola has a Linux-Java based platform called MOTOMAGX. It is not an open polatform, AFAIK. Also, Motorola's mobile division's future is uncertain rigt now.


• Openmoko is trying to create both a software platform and hardware; they release the design to the hardware as well.


• Ubuntu Mobile
.

Nokia recently joined LiMo. Does this mean a Googls vs Nokia fight in the mobile OS arean? Not to mention, Symbian OS and Windows Mobile are the current dominant players and already have application developer mindshare.
