Surface RT sucks, when the Pro gets released is when it will actually have some descent sales. If anyone was going to buy an ARM device, they should get an ipad, or a nexus, or a transformer tablet, not a surface RT.
Out of all those 17.4m activations, I would have liked to have seen how many were Android vs IOS. I guess Flurry didn't want to see Apple stock take any more of a beating that it already has.
