I agree with cheald on this. Fragmentation is only a problem if it actually leads to additional difficulty of development for those platforms. And the irony of the current situation is that the "fragmentation" we're seeing now is likely responsible for the fact that web development is "easier by the day." The worst situation, which we had back in the late 90s, was increasing domination by one player intent on subverting standards to push its own platform. Then innovative platforms get pushed aside for expediency's sake. Wrenching the web back from Microsoft resulted in many years of difficulty, but now we're in a situation where everyone, even Microsoft, must adhere to standards or be left behind. The very best outcome for web users will be for the market to stay as "fragmented" as possible, so everyone will be forced to stick with standards, and nobody ever gains a large share that can be used as a lever to distort the market.
