The obvious use of an iPad or Asus tablet is to hook it up to a projector and show a room full of people what's on it. That can be interesting, and if you've got a special app that only runs on that tablet, then it's somewhat innovative.
One thing we've been less successful at is in changing the way a class of people can interact. We already have clickers (so they're NOT next-generation, at least in my own opinion). There are smart phone apps that double as clickers... new-ish, but it won't set the world on fire. One thing we wanted was peer-to-peer connectivity so that students could update the teacher's device, perhaps showing up on the screen. The iPad/iPhone app "Whiteboard" can do this, but only when peer-to-peer is working (so, not at MRU, but it works great in my house on its wireless connection).
Here's what I've got that's a bit new. Using a blog with multimedia assets. And now I've created the Frankenmovie. It's got the Mac's Screenflow program displaying iPad's ExplainEverything on it!
I'm going to have some fun with this, I think!
