Classroom 2.0 technonlogies

Here at my school we have a blank slate, so to speak, in regards to technology. We are trying to put together a "Wish List" of technology in our classroom. I am a big thinker but I also know that there are a lot of even "Bigger Thinkers" here. I know we won't get everything on the wish list but I don't want to miss anything. Please help me compile a list of the most "cutting edge" technology that has, or could have, an applied use in a Project Based Classroom for teachers and students. What tools would YOU WANT?!

Thanks for the ideas and imput - Please think HUGE!
