Make them power users so they can’t install programs and the like.

I just made a point about this too…

As a computer engineering student, I’m as skeptical about my browser as any one. But, as a class assignment, my friends and I conducted studies of mozilla and ie7 side by side and mozilla didn’t win. As a matter of fact ie7 came out in front by quite a bit including on the machines of the already determined mozilla users. Check out symantecs internet security report, and you’ll see the blessed mozilla isn’t so wonderful at all.

Sorry to burst anyone’s bubble.
