Arguing of sales numbers doesn't work for the N9. It was a dead phone walking when it was released: The Microsoft partnership had been announced, Elop already had publicly stated that whatever its sales numbers MeeGo wouldn't be continued and it wasn't even sold in major markets like the US (here in Germany a few shops imported them from Switzerland!). Of course it (and more importantly the platform) didn't stand a chance like that.

(I'd tend to agree with the second point that MeeGo would have had difficulties and likely would have failed later, even if they'd focused on MeeGo and the N9, but there was something to it)
