I'm in high school currently, and my school has no macs. The school updated everything when I was in 8th grade (it was mentioned extensively on the tour about the "Incredibly Fast Pentium 4 Processers"). We have three computer labs with PCs running XP, and every classroom has a computer. Also, the physics, chemistry, and bio labs are equipped with laptops, also running XP. However, some teachers have MacBooks (that they have personally bought), and can use those because all of the attendance and grading is web based.
