At just 2.8 x 2.9-mm (smaller than the head of a matchstick, and thinner than a stick of gum), Epson’s Infineon XPOSYS Assisted-GPS chip could literally bug the heck out of you. Smaller and more powerful than any A-GPS before, it can even track indoors. On the plus-side, you may never loose another left-sock again.
