Microsoft's Principal Researcher Bill Buxton in an interview with The Globe and Mail said "The next big thing in tech, he says, is something like Microsoft's already available (but super expensive) Surface. So what does the next version of the Surface look like? Well, it's going to be much thinner -- "no thicker than a sheet of glass," but most importantly, it'll cost much much less. The man who helped design what ultimately became Surface says that soon enough, the cameras will be embedded within the device itself, making it a low-cost, in home product rather than the niche product it is today.
Buxton also said in the interview that he thinks we'll begin seeing home implementation within the next three years. We sure hope that he's correct."
