"Final nail in coffin"... I don't know

What choice did they have? Android is buggy, unstable and pretty much a platform built on unlicensed code from other peoples work. It may be experiencing huge growth now, but most of the people I now with an Android are unlikely to buy again

Apple? Clean easy to use system, but looks dated now and lacks real interaction with the user - relying on standalone apps

WP7 Mango is super quick, slick and very easy to use. It provides much fusion between the user the unit and their data in a much more interactive way and a system you could easily give to a new comer to smartphones or a poweruser

WP7 just needs some slick hardware to show it off - HTC Titan is coming, as is the new Nokia range based on the beautiful N9

Maybe times have changed regarding market dominance (I think it will be much more of a shared market) but with this essential restructuring, they will be back in the leading pack in terms of relevance

...And all with Navteq mapping onboard a successful WP7 platform and built in to Bing, could help Navteq too
