The first is obviously true, and I'd argue the second is as well. An effective duopoly of iOS and WP7 would be bad for consumers in the short term due to decreased competition, and even worse in the long term due to the effects of all mainstream mobile platforms being locked down.
Well not really; it's basically in Google's interest.
Not mutually exclusive.
To say nothing about their own 3.14 billion dollar bid for Nortel's patent portfolio and then claiming that their true worth was 1 billion, being completely disingenuous.
How? Google's claim is that if the patent system were fixed, Nortel's patents would be worth much less than they are in the current environment.
