There are already smartwatches and other wearables with cellular data built-in, but the bulky hardware they need for that wireless access makes them less than elegant. Intel clearly isn't happy with this state of affairs, as it just unveiled an extra-tiny modem that should put truly sleek, always-connected devices on your body -- and seemingly everywhere else. The new XMM 6255 isn't much larger than a penny (0.47 square inches), but delivers a full-fledged 3G data link. It's built to take abuses like power spikes, and it doesn't need a big antenna to get a good connection; it can even get solid performance in a low-signal area like your basement.
