Query: WOW! Nice Device for the road warrior

The fact that you can now interact with your audience and still maintain control of your laptop presentations makes this a great way to polish your presentations.The set up with the s/w on the CD was a bit confusing, but the device works even when you are not pointing it at the laptop. It's is a bit bigger than it looks and what the product literature makes it out to be, but they ship it with a nice neoprene carry case that will help protect it from the bumps on the road.This will get a lot of use on the road with me.
