In a smoke filled room
Man from MS: I see the percentage of Windows-based systems you've been selling has decreased lately.
Man from ASUS: Yes, although we sell many Windows systems, we believe in offering our customers choice, and some of them choose not to use Windows, so we feel we should not be charging them for Windows.
Man from MS: You do know that your "most favoured partner" volume licence deal requires you to ship xx% of systems with a Windows licence, otherwise your Windows deal changes and we will have to charge you closer to market prices, which will make your products less competitive against other "most favoured partners" such as Dell and HP.
Man from ASUS: Hmm. I see what you mean. Is Windows 7 ready yet, because Vista is an irrelevance in this market (and elsewhere) and you know it.
Man from MS: Don't worry, especially for you and our other "most favoured partners" we are extending the sales life of Windows XP, and Windows 7 GUI is being leaked as we speak, to make people think we feel their pain and intend to do something about it.
Man from ASUS: Excellent. Trebles all round.
Have a nice weekend.
