Choi reasons out his choice because:
“It’s not right that acquiring an operating system is becoming a fashion.”
So, while Samsung wants to release as many devices as it can at every conference, it seems that it'll only allow a few operating systems to be on top of them. Android and Windows Phone seem to be the norm in the US, but if Samsung's decision not to become a partner for another operating system, we may see Bada hit stateside sometime soon.
