Xiaomi has unleashed a 399 CNY ($64) action cam onto unsuspecting cats in China, but will it join the Mi band in the US? The Yi Camera actually trumps the specs of GoPro's entry-level camera with 1080P, 60fps video and up to 64GB of memory at about half the price (the $130 Hero has 1080/30p video and 32GB max storage). It also weighs significantly less at 72g, has a bigger battery and can go the same 40m (130 feet. Update: separate case required) underwater. To be fair, unlike the Hero, it doesn't come with a housing, mounts or the impeccable rep. But Xiaomi is offering a bunch of extra accessories, including a helmet mount and, yes, a cat harness.
