[citation][nom]ikyung[/nom]Samsung already has their mobile OS on phones. They been testing it in S.Korea for a while now. The reason you don't see phones with the Bada OS from Samsung in NA and EU is because it probably isn't ready to compete with Google, Apple and Windows. But, now teaming up with Intel, they might have better leverage here in the west.[/citation]
Actually Bada is available in Europe, in fact pretty much everywhere except the US. As for not competing, it actually has more market share than WP7. The lack of quality apps is where Bada can't compete with the more mature/popular platforms. The OS itself is very competitive.
