The university I go to gives everyone laptops. It's those Lenovo T60/T61/T500 ones that you see insurance agents carrying around. They charge all the students $1500 a year for them.
Now I'm in engineering so for me this is a bargain because the half dozen programs I use would bankrupt my parents. The CAD program alone is $20,000 for a license.
BUT, business students, science students, health science students, and all the others don't use any programs except Microsoft Office and for them $1500 a year is robbery.
And no matter what class you're in if I look around during a lecture I see MSN, Facebook, Top Gear, and some other stuff. And if you go to the back 2 rows you see Warcraft and some online FPS I can't remember the name of. Guess how long those people lasted.
The difference is that the only practical use of a netbook is surfing the internet. They're often not powerful enough to run more than browsers and word processors, and their keyboards are too small to be typing for longer than email length.
