this announcement says Nokia will help shape WP7... sounds like a great combination to me!
As I've said before, industry experts are saying that in approximately 4 years mobile processors will have the same processing power as today's low-mid range desktops.
Other companies put WP7 on their phones and no one screamed that companies like HTC or Dell were going to go out of business as a result. Why is this going to kill Nokia?
Saved tens of billions that buying Nokia would have required.
