It's been some old and recent news about microsoft working on products such as project natal and Microsoft Surface to name a few. Taking Science fiction to reality. I'm a guy who never says "bull$hit, that can't be done" when watching science fiction movies, I think mostly everything can be done, maybe not today but in the near future, next year, next month, who knows.
Do you remember watching "Minority Report" movie? Some old folks or not so tech-guys would say, that's insane, so impossible but actually it's been done, it's being under development and almost ready to be released soon and have one at home and stores.
Watch some videos:
ps. Say goodbye to your wii, this is insane.
