I've been waiting for a basic device that just tells me roughly what brain state I'm in (alpha/beta/delta/theta/gamma dominant) with bonus points if it has a feedback mechanism to make it easier to train one self into a certain state. I don't think they got the pricing right. There are already quite a lot of consumer EEG devices on the market that either do more and/or are cheaper. http://en.wikipedia.org/wiki/Comparison_of_consumer_brain%E2%80%93computer_interfaces http://en.wikipedia.org/wiki/Comparison_of_consumer_brain%E2...
