Incidentally, I didn't use the insane comment as an insult, but rather that Microsoft doesn't really do anything without trying. At least without trying FOR something. There's always a goal. They spent a lot of money developing a promoting Zune, but they recognized that there was no way they were going to split the market in half over night. Perhaps since the Zune's introduction they have scaled back efforts or simply let their efforts wither, but they did give it a go. I suspect they're regrouping and will leverage what they've got with Windows Phone, the same way Windows Phone was built on Zune DNA to begin with.
