Why don't we have augmented reality?

I keep seeing brainwave reading headsets being used in toys and computer games, I also recall seeing VR "sunglasses" for watching iPod movies in those "SkyMall" catalogues on airplanes. So I ask, why has no one combined the two yet? The EEG would allow someone to work a attached smartphone without touching it and the glasses would make bending over to look at it unnecessary, though the level of concentration required would probably make texting while driving ill-advised. Also it would allow Virtual reality without those bulky gloves. Granted it would be expensive, VR glasses often cost $200-$500 and the cheapest EEG headset I saw was $99, but the cool factor alone should make it profitable (you reading this, Bill Gates?)
