The “limited edition” white Nexus 4 has once again reappeared on sale in the U.K., and has exactly the same specifications as the original black model, the only difference being a new lick of shiny white paint on the sides and back.

Yeah, I said it. Google should — and probably will — sell an Android TV.

No, not a dongle. And I’m not talking about a Google TV of the kind you can buy today in which Google technology puts the “smart” in the smart TV feature.
