Last week at Mobile World Congress, we got a peek at the Samsung Gear 2, the updated version of the smartwatch intended to get a jump on Apple. There's been a few changes: the strap is swappable thanks to moving the camera to the watch face and the whole thing looks sleeker. You can still use it to make calls, but the operating system has shifted from Android to Tizen, an open platform Samsung has been working on. That also improves battery life, giving you up to three days (Samsung claims), and allows you to customise the appearance of the system.
