Actually I think just having the head tracking for your view, while sitting in a fixed cockpit with your hands on static controls (HOTAS), will make this a killer application for flight sims and similar simulations. There's already head tracking for flight sims that lets you move your view around (TrackIR, Freetrack) and having relatively static controls like a HOTAS means you don't have to worry too much about looking at your hands. I ordered one of these dev kits and am looking forward to trying it out like this.
