There was also Bada OS, Samsung's attempt to cut the dependency on Android. I was actually running a device with 1.0, and it was surprisingly usable. The investment in building a development community was also there. They released lots of documentation and the SDK. Sadly, they followed with a 2.0 that really wanted to feel like Android (but wasn't).
They obviously didn't want to put all their eggs into one basket and kept releasing Android phones in parallel. Eventually, Bada died a silent death, although some of it probably found its way to Tizen.
