Samsung’s wearables strategy seems to be: “Throw everything at a wall and see what sticks.” In a little over 12 months, the electronics giant has launched six — yes, six — different smartwatches, each with its own unique personality.

Yep, the Gear S actually has a 3G modem inside it, along with WiFi, Bluetooth and GPS radios. It’s basically a watch that’s also a phone. You can even respond to emails using a tiny onscreen keyboard. But, at $350 a pop, can it replace your phone? And more importantly, would you want it to?
