I think it is very important to have guidelines in the classroom for the use of technology. This isn't just to prevent the kids from doing something bad, but it also lets them know that sometimes you accidently go to an inappropriate website and it informs the kids what to do from there. However, sometimes kids can abuse technology and it can be harmful to the other kids in the classroom. For example, a kid can type something mean about another kid and either show it to other kids or they could even print it off. If this is the case, then you should just rely on your classroom rules about respecting others. Technology is a great thing to have in the classroom and it can stay that way as long as the kids know their boundaries.
