Will European PC Users Pay Microsoft's Bills in EU?

If most Mac users will not really care about Vista launch in Europe, the price policy established by Microsoft for EU markets might push users to consider Apple and its OS.
Why? Let's look at some points:
- Microsoft offers 4 different versions of Vista (without mentioning the update versions), and at the end most users will not really be able to choose the one they really want, and their needs might evolve over time. Big head hake for consumers.
- Price of Vista licenses in EU are almost twice the price applied in USA!! The basic version costs 279€ while the full complete version will be available at... 575€. One can really seriously ask if Microsoft is acting this way to make European consumers to pay bills imposed by European commission following monopoly infringement in EU?
- when compared with Vista, MacOSX Leopard that should be sold for 129€ might look very cheap, without limiting users in their needs or usage with some weird version-dependent features as in Vista.
So after relying on iTunes for encoding music tracks of its own online music store, is Microsoft investing in advertising campaigns aiming to promote Apple products?
