I looked up the website forthe Trac IR and have a question...how much play do you have between the link? Example.... To look behind you how far away from the screen do you have to turn your head to get it to look behind you? If I had multiple monitors it would be awsome...buuuuut, I'm wondering if its even worth the effort since I'm running on one. It'd be a little uncomftorble rotating my head one way and trying to still look back at the screen. Just curious, it looks like an awsome hands free deal.
