They've changed the way some hardware interacts with the OS but if anything, it's supposed to make it better. But hardware manufacturers have been very slow to react, and ultimately it's more their fault than MS's - they have known about the changes for 18 mths. MS can't publish roll-out dates until they are certain. They've been notorious for running late, so rather than be more realistic at the outset, or perhaps improve their performance, they've adopted the tactic (as have many others) of simply not announcing launch dates until they are 100% certain that they will be met. If they are saying H2 2007, they are thinking October but will probably end up releasing it in December.
