I'm excited about this and even tried to reserve one (no reserves for people outside the US :S) but I do worry a little it might vaporware. Lot's of researchers have been working  on these kinds of systems for years but the technology has been very expensive. Emotiv's website has a few renderings of a prototype and a little bit of technical information but as a whole the info seemed a bit incomplete. I have no doubt this technology is coming to home computers but I'm not entirely convinced it will be this year. When it does come I certainly will be one of the first in line for it.
