and the 808 is my next phone for sure.
I see a big drop in N8 sales coming, a disintegration of mid/low Symbian Belle phones due to the Lumia 610.
The world doesn't stop. Everything changes, and the mobile industry changes faster than anything else. I am sure a real Linux phone like the N900 will emerge eventually, maybe real soon. But it will not come from Nokia, and it will not be a flagship device this time around either. Flagship devices are made for the general public, not for a small group of computer geeks (unless you count Android as Linux that is).
My bet for the next Linux phone is a Samsung device running a Tizen/Bada blend on Intel chipset or ZTE running some home-brewed Android like Linux on whatever chipset they get their hands on, maybe even both. But first, it's time for some 41 mega pixels
