I can see a major role for tablets in schools. For a start, many textbooks are already available in PDF format, as are language dictionaries. So instead of carrying around a pile of books - often "forgotten" because they are big and heavy - one small tablet will do the job. Also, for maths, there are many excellent packages, which I'm sure will be migrated to tablets if they don't already run on them.
Throw in internet access (hopefully for research, not Facebook), and having one's own tablet in class seems like a good idea.
However, I think too many people look no further than Apple. Consider other offerings such as Toshiba. They may not seem as sexy, but many are just as functional and have higher-resolution screens. Also, you won't be restricted to Apple software.
