Obviously none of these people are animators
Bottom-line if he's in the school for animation he's going to need windows. Applications like Maya and 3d studio max are not nearly supported enough on OSX. I'm a big mac fan, and I have one for home use, however at work (i work in the industry and also have an MFA in animation) everyone uses either windows or linux. Macs only come into play if someone is doing graphical 2d work like painting textures in photoshop, or video editing. Granted he could always use boot camp to install windows on a macbook, but then you're paying up for lesser hardware. I'd take a look at the hp envy line, they seem to be the best equipped pc laptops at reasonable (>2000) prices. Anyway, that's my two sense, people tend to recommend macs for everything graphics, but animation is a different animal all together.
