As the line between fashion and technology continues to blur , Microsoft Japan is taking the well-trodden path of fashion collaboration to promote its Surface Book and tablets. Microsoft has claimed a corner of the upscale department store Isetan Men's in Shinjuku, Tokyo, stocking its hybrid PCs next to pricey fashion items. There's also a digital "hologram" mirror, which shoppers can use to see how they look in 360-degrees. Shop attendants scan you with a Surface -- of course -- while a platform spins you around. The results are then beamed to a floating display so that you can see how you really look. Browse the department store collaboration for yourself in our gallery:
