all of the teachers at my old school used macs, and they had the students use them too, personally i like them. i love how they have the web cam, cool video editor, garage band, and how fast they run. I was the editor of the yearbook last year and used the macs at school, and a pc at home.
I really liked the macs, but i am used to a pc, thats the only negitive side to them in my opinion. if you are used to a pc, it will take a little while to learn how to use a mac.
and that mac book air thing is rediculous! i hate it, it is too thin, i bet if you dropped it or set it down roughly it would break. i like the small white ones [macbook] they are cool and my friend has one.
good luck
