I hope Microsoft have learned from the Vista adventure that they dont have the capacity to re-invent a OS in one try, they should really do what Apple have done for the past six years -releasing somewhat minor but still substancial OS upgrades every year that really pushes the user experience forward.

Look at the 90's -3.11->98 was within a 5 year timeframe, NT 3.1->4.0 within just 3 years and all of them was a substancially upgrade for users

Another thing, if the pricing rumors for Vista are true, well this user just wont buy it, its not worth that kind of money.
