Bada is TouchWiz, yes kind of, what the android stolen parts are, you have to explain. The core is Nucleus, an OS Samsung has used long before Android even was a thought, and the predecessors of TouchWiz /Bada has existed almost as long and was used on Samsung Windows Mobile phones and Symbian among others.

Harmattan is innovative, Swipe is innovative and using Qt is innovative, the way it is used, but it is still Linux. Bada is something completely new, better, more efficient, a multitasking smartphone OS developed based on a true RTOS for embedded devices, an OS that is used in more devices than the grand total of Linux based installations ever. That is the kind of OS ZTE and Huawei needs for most of their devices, and they already have most of it, they are using it in their dumb-phones. For the top brass, they already have Android and WP and even MeeGo if they want. I can't possibly see what use they have for WebOS, a one-off that already has died, twice.
