Microsoft's Steve Ballmer was his usual frank self when he met financial analysts yesterday, admitting that the world isn't yet as keen on Windows Phone as he'd hoped. To be precise, AllThingsD reported him as saying: "We haven't sold quite as many as I would have liked in the first year." His cunning plan? Well, that's easy: make it all Nokia's problem. Or, as he put it: "With Nokia we have a dedicated hardware partner that is all-in on Windows Phones." Indeed, the Finnish manufacturer has now staked far more than Microsoft on the success of this "third ecosystem" and, if its imminent Mango handsets fail to turn things around, we may eventually see Stephen Elop standing behind that silent cash register.
