I don't know how much advertisement will affect on me. I am a full-time Linux user (at home). My 2nd main computer is Mac. I used to be a Windows users -- that was five years ago, so I have not switch back to Windows. I do have Windows XP Pro in my Laptop due to office application, and required by College. Otherwise, you wouldn't never see me using Microsoft. As far this advertisement, I believe it's a part 1 of whatever they will throw at us in future.
