2.-5 million LUMIAs sold in the first 20 day period worldwide.....
The 920 isn't supposed to be the best selling Nokia phone. Just like the Corvette isn't supposed to be the best seller for Chevrolet. The 920 is there to demonstrate that Nokia makes better phones than Apple or Samsung. Most people, especially in developing areas, aren't going to be buying those they're going to buy the lower end phones.
Nokia sold 77.3M smart devices in 2011 and 339.8M mobile phones and they lost a lot of money doing it. The top-end Lumia's have sold around 1-4 M /quarter since they came out. If you're counting on 2.5M phones every 20 days saving Nokia then they're screwed. Bottom line is, the Lumia sales are up but your perspective on how Nokia makes its money is way off. The 920 sales are going to be a very small percentage of Nokia's revenues.
" If you're counting on 2.5M phones every 20 days saving Nokia then they're screwed."
2.5M Lumia 920 every 20 days would imply over 10M per quarter for the highest end model only. Nokia would probably become break even or profitable right away and stock trading at 10. For the record, I don't think any of us expect they are selling 10M/Q L920s currently. Maybe all Lumias combined at best case scenario? That would be a terrific start for WP8. But your statement above is not correct in my opinion.
