When it comes to ultra mobile PCs you can’t get more mobile than a smartwatch. I’ve tracked the technology for years and over the last six months I’ve given three very different smartwatches a long-term test. I’ve recently been using the Samsung Gear S2 Classic 3G eSIM model and it’s an impressive bit of kit. GPS, WiFi, 3G, Bluetooth and an operating system that’s controlled with touch and voice. I’ve also been using a fitness-focused band from Medisana and the Basis Peak which sits somewhere in the middle between a smartwatch and a fitness band. I’ve learned about what I need, what people need and have now some thoughts about the future of smartwatches.
