I'm also a law student and would love to see this feature added! My 1L professors used tables a lot to compare elements between uniform statute, state statute, common law, etc. I agree that it's pretty inconvenient mid-lecture to create a table in Word and then paste it in. Not only is this difficult to do when your professor is going through the material quickly and not putting it on the board, but it also creates extra steps if you need to go back and change something in the table.

And speaking of trying to get stuff down quickly, I would love the equivalent of Word's auto-correct (which I believe is possible through Snow Leopard's "substitutions" feature). I'm still using Leopard, but having auto-correct would more than motivate me to upgrade to SL and the latest version of OOP.
