One "theory" is that the release date is fall, so partners like Dell and HP can build one too. Hard to say if Ballmer is delaying price points in order to allow partners to get a product, either made by and sold through or their own versions.
RE: Hard to say if Ballmer is delaying price points in order to allow partners to get a product,
All I can say is I have seen Ballmer present Microsoft’s latest products more than once. I have also seen Bill Gates before him in action.
No contest, Ballmer is the more flashy showman/salesman (or BS artist is you are a cynic).
