Ken,
Happy New Year.
I agree re sales. Shame- WP7 is quite a nice UI and the prospect of consistency across apps will be refreshing for anybody who lives in the Android jungle.
Part of the issue is that people aren't as easy to wow as they were when iPhone first came out. And the market now has expectations that prevent serious OS innovation such as form factor constrained by a user's pocket or purse and an overall UI experience that demands consistency across devices. MS was smart to offer Halo etc which definitely is a distinguishing feature, but obviously not enough to cause a groundswell. IMHO MS is going to need a *big* difference point like reliable speech-to-text or a really smart agent (not like that awful paperclip) to create enough zing to cause mass migration. JMHO.
"... 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
