Was it going to be Microsoft embrace/extend/extinguish, or a case of promoting it to world class software?
Sadly the jury is still out on this.
Its a bit of a shame that worries of the Old Microsoft follow the New Microsoft so doggedly, but your skepticism is understandable.
Speaking generally, and from the inside, I can assure you that the new leaf really is genuine. If you consider the corpus of all the announcements made last week, and the sheer effort or expenditure that it took to make them happen, I'd hope that'd go a long way towards convincing you of the new strategy.
