LOL re the ads. I'm afraid it's "game over" as far as WP7 is concerned. Even if MS buys Nokia and Blackberry they're barely half iOS's position and can expect to keep losing the Symbian and RIM users , mostly to Android which now has locomotive momentum. Shame- cozy duopolies are no good for consumers in the long run.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
