CES 2010: How soon will Nexus One be eclipsed?

The reviews are mixed on the Nexus One, the new smartphone -- or, as Google puts it, "superphone" -- announced by Google yesterday. It's an Android 2.1 phone for the T-Mobile network, for now, with availability on Verizon Wireless in April. On Betanews, the decision is split between whether Google has signaled the next revolution, and the revolution having already started without Google. The question today is, how long is Nexus One going to be the model of everyone's dreams, and by "how long," I mean, how many hours? That's the subject of my conversation this afternoon with Betanews contributing analyst Carmi Levy.
