What Google's Nexus One means for carriers

Now that we've seen the dust settle around Google's entry into the mobile phone business, what are the real takeaways and impacts of the move - particularly for traditional mobile operators?

1) Decoupling phones and carriers.

2) The "Find-Stuff-Phone" -- Android phones are built from the ground up for searching the Web, navigating maps and directions, finding local businesses - all search-driven functions that Google has taken great pains to (a) own and (b) be able to offer for free while monetizing with advertising.

3) Monetizing Voice -- voice service becomes just another data object on tomorrow's IP-driven wireless architectures.

4) Customer Service Quagmire -- Customers buying hardware and service contracts need more hand-holding.
