Are you forgetting 50% of the reason for buying a Mac - OS X? Some people just do not want to deal with Windows anymore with all the bugginess, crashing and viruses. Even I as a lifetime Windows user have to admit that fonts are drawn better in OS X and the overall UI is more consistent.

I agree with maflynn here. W7 has really improved experience comparing to XP and Vista. I never even installed Vista but have been running XP in both 32 and 64-bit flavors for many years. As one of my systems runs OS X and 2 run W7 I must they both have strengths and weaknesses. I won't go into severe detail here as it would take a while but let's just say they're on par with each other for every day usage by most people.
 
Until it is technically impossible to run osx on non apple hardware (no Eula rants please), the only apple tax I will happily pay is for iOS devices and Apple software.

Can we stop bragging about illegally installed software then?
