2.-5 million LUMIAs sold in the first 20 day period worldwide.....
" 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.
Last year they weren't selling expensive models like Lumia 920. Most of them were inexpensive Symbian phones. They also cut a lot of operating expenses since then. The way I look at it, I compare to other companies making money on high end smartphones. Samsung sold 18M GSIII last quarter and made a ton of money. Apple sold 26M iphones Q2 2012 and they are a $500B cap company mostly due to iphone. Now, we know profit margin for Nokia is not going to be as high as Apple, but I don't think 10M L920s per quarter is a figure to be laughed at. In fact, I think NOK would rocket to 10 or higher based on that alone. Again, I don't think we are quite there yet though.
