content: given the amount of money microsoft has been pouring in, I'd say its an utter failure. They've been predicting it would hit 10% in no time, but its been over 3 years now AFTER a year of lead time. they are going nowhere.  They even rigged up nokia to self destruct, so that they could buy only the wanted parts of nokia. They thought imaging would be their killer feature, now in 3 years the competition has caught, its no longer their best bet.  as for enterprise, they may have a leg up there, but they are losing the advantage slowly because of lack of adoption and android having pretty much won the mass market space.
