Yep, looks pretty awesome. Certainly cool, but hardly "revolutionary" as I can't imagine it replacing any existing techs. And the name is pretty misleading, as it's not "holographic"; it's simply a really good augmented reality system.
Yeah, I'd imagine it would be like what the N64 was to gaming. A big step forward but not revolutionary.
Well I guess the N64 is totally off-topic here, but I wouldn't speak so modestly about it even though I never had one. It was the first console to have an analog stick and it had some hugely important games. I would equate it more to the Dreamcast-- really awesome, but probably won't catch on because another tech will leaprog off of it to much more fame and fortune.
