Nokia was already all-in on WP7. Which is kinda why their stock is in the toilet right now. Investors are rightly spooked that Nokia threw literally everything the company has ever made in-house into the garbage to license an OS which was already having dubious success in the marketplace, and then their licensor just threw everything in the garbage themselves to start over. I mean, how many abrupt OS transitions can a company realistically survive? Nokia is really trying to set world records here for how many OSes they can abandon without the company exploding into a fireball and burning.
Agreed on the latter half of what ya said. By "all in" I mean we've yet to see a fully Nokia built and designed phone from the ground up for a Windows Phone OS. The 800/900 were tweaked versions of an existing N9 model. I'm just hoping they manage to pull off a solid phone the end of this year and even further into next year with some PureView tech. I love their phone design\hardware, IMHO it's distinct and the only company giving Apple some competition in design.
