Simply put, what accessories should I get. And what should I avoid? I use it for racing games, movies, and music. Already got Netflix on there, and already streaming media from my computer. But, I'm talking about hardware. Are there any Transformers related gadgets out there? I've seen the awesome Tron-based controller for it, what else? Still looking for a good desk-top mounted steering wheel to use with my racing seat set-up. Do not want the lap-top kind of steering wheels. What other accessories are out there?
