Sales figures ? They didnt make enough units to sell like Iphone or Samsung, it's not mass production.
It's 'limited availability', regardless what gsmarena said, means limited edition.
Means it's not intended to sell a lot, due to Mr Elop.
But the Nokia staff seem very enthusiastic about it.

You want one? Oh sorry, sold out, there's only 200 units. Or 100 units. N9 is the only Nokia model positioned that way, as in 'get it before it runs out'
