@Bas: Not being able to buy a Surface in PC World is also an issue. Apple cater for people with money, Android caters for people on a budget or who see through Apples extortionate business model. Windows has never been about prestige, with Windows 7 running in a Warehouse as well as an Investment bank.
The direction Windows 8 has taken with the tablet, is to target people with money, If they had called the tablet OS something else (like Xbox or Kinect) they might have had traction, Windows is far too entrenched a product for you to tell us "re-imagining" it suddenly makes Ford start producing Ferrari's. This is where they have made a misjudgement.
