Is there any example in the history of desktop computer of a manufacturer trying to customize an os so much in order to try to replace it later by its own ? I don't think so... With the complexity of today's app, which become close to yestersay's desktop one, it seems like samsung goal is really unreachable. They've tried it with bada without luck, then tizen, and now they're doing it with android. Maybe what they're trying to do is not to get rid of android, but rather to create its own fork, just like amazon. That seems like a much more manageable ambition.
