I sincerely doubt that a marketing push will help. Consider Windows Vista--for all the marketing it had, it failed to win any fans and the commercials were considered incredible blunders. Microsoft has never been known as a successful marketing company--only a good strong-arming litigant and known for winning through underhanded means, not by marketing (i.e.: these examples). Better still--consider, again, the Zune. It had a major marketing push--a very insistent one that backfired: on release day, they called the press together to announce the new ZUNE and asked all the members of the press at the event to throw their iPods into a bin in return for a brand spanking new ZUNE from Microsoft. NOBODY in that press event took them up on that offer and it turned into a PR disaster.

I strongly suspect that Microsoft will NOT be able to win this by marketing, no.
