At a time when phones seem to be getting bigger and more cumbersome, it’s great to see the Japanese carrier, NTT Docomo, develop the Kyocera KY-01L, which is not just tiny but also ultra-thin. In fact, at 5.3mm thick, it’s slender enough to slide into one of your wallet’s credit card slots! It will set you back 32,000 yen, or about 285 USD but sadly, it’s still only available in Japan.
