Currently the only two Operating Systems that really matter are Android and iOS. Balckberry is a distant third and very well may make a comeback with BB 10. But Tizen seems to be getting more and more buzz ever since they had it running on a Galaxy S2 HD (it actually looked more like the leaked GS3 pics in a case). And unlike other open source OSs that attempted to challenge Android, this one is back by multiple big names like Samsung and Intel and it can run on Now we know Samsung is the biggest Android vendor, but you gotta wonder, are people choosing Samsung more than they're choosing Android when they buy a Samsung smartphone? Because if they are indeed picking Samsung first, then Samsung can very well end up dominating the market on a whole new front. Your everyday user could be going in to buy a GS5 running Tizen, and have no clue it's running Tizen. And considering Tizen will run Android apps, the average consumer couldn't care less what OS is on their Samsung device. All the while Tizen gains market share. To me Tizen can make Samsung a company that is very much a hybrid of Google/Apple.
