Isn't it a little too late now? WebOS is way behind in terms of functionality compared to Android and so even someone picks it up they need to spend considerable time and resources to bring it up to par to compete with it. It has to be some company that does not mind waiting and spending the resources. I don't see any one in that position right now. Unless this is purely a move to generate excitement in the developer…
