There is a second element in the NOKIA/RIM/MSFT/AAPL/GOOG that I wish someone like Asymco or JD Powers would track - and that is "Consumer perceived value 1 year later" - I realize WP7 hasn't been out for a year yet, but most of the other platforms (is Nokia still a platform?) have, and it would be interesting to see if people still value their smart phone after the initial wow factor has worn off, or whether they have seen a decreased, or increased value.

It's complex - because a lot of factors come into play. iPhone has better battery life (as long as you don't touch the GPS), Android has more freedom, WP7 has a nice engaging interface, RIM is unbeatable in messaging, etc...

But, it would be nice to see what people think of their smart phones a year after purchase, and add _that_ into the unweighted graph [1] of Profit/Market Share/Revenue Share that Asymco does.

I guess, to some degree, that's represented in a "Will you buy the same model during the next refresh" - and the answer to that question might be a good proxy for "How happy are you, one year later, with the value you receive from your smart phone"

That, too me, will be a key indicator of which of the mobile providers will prevail.
