None, that is the answer, at least as smartphones are concerned. I don't see any reason why MeeGo should be a great smartphone OS, at least not for some time when HW has evolved some more.

iOS has to be taken out of the list. iOS isn't sold separately. iOS and iPhone is one inseparable package. In a similar manner Symbian and Nokia is one package, at least that is how most people see it even though it is not technically entirely correct.

What we are left with that has some reality behind it is Android vs MeeGo on tablets. You may argue that people want Android. I say that is just US blogging nonsense. People want value, they want the web (and everything with it, and lots of it), they want HDMI, they want quality. The name of the OS means nothing. They want this The WeTab already outsells the iPad. That is what I have been trying to say. Get out the leeches, add value instead and it will sell. That is MeeGo.
