I believe this is Samsung’s attempt to control an ecosystem without being beholden to google or anyone else. Tizen will already run android apps so there will be no shortage of apps when this launches. Samsung’s manifestation of Tizen is already skinned with their Touchwiz shell, so for the average user, they might not even notice as it will look like the other samsung offerings with touchwiz. I am far more interested in the Upcoming Ubuntu interface, the Firefox Mobile OS and especially Jolla’s Sailfish OS.
The problem with Tizen is, first, risk of salmonella, and second, if you get the phone too close to your head, it’ll bite your ear right off. Thanks Ernest.
