Although the tablet market is humming along with three mobile operating systems, the first signs of a fourth are starting to appear: Tizen.
[click to view image]Although Android was created to be an open-source operating system, there are some who believe it's too much under the control of Google. That's why Samsung, Intel, and others have joined together to create Tizen, a Linux-based alternative.
The first versions of this were intended for smartphones, but the Japanese company Systena has introduced a develop kit for tablets. This consists of a 10.1-inch tablet running a modified version of Tizen 2.1.
At this point, it appears that some of the larger companies that are backing Tizen -- most notably Samsung -- are doing so to hedge their bets with Android. If Google really starts treating Android like a proprietary operating system, they want to have an alternative waiting in the wings.
