You guys sound ridiculous. You also misunderstood the stats. These stats relate to apple vs. Dell, or hp etc... The hardware makers. Its not about apple vs. MS.
Macs books are amazing machines, yes expensive, but far more than just status symbols. The are the best laptops from a hardware perspectuive. They are the most rugged (aside from $$$$ tough books), fastest and least problematic mahines of all the manufacturers.
You don't get viruses on macs, security is not an iusse. It's no brainer for a student to prefer a Mac over a windows machine. I for one am getting fed up with the virus and security problems on windows. I have been burned too many times and lost too much of my time over these problems.
That alone is worth the premium cost.
I am a long time windows user and never liked apple but I do know they make excellent and highly productive mahines.
Oh yeah, apple gives away iPod touches to students with Mac purchases during the back to school season. Small factor
