Smartwatches are already well out there, but Sony has gone for branding gold with the Sony SmartWatch, a tiny slab of Android-based tech that pairs with your smartphone via Bluetooth—think  supercharged smartphone remote! At your fingertip, touchscreen control over calls, texting, email, Facebook and Twitter, calendar, and music, for a start. Grab apps, over 60 and counting, from Google’s iTunes for Android, Google Play, to extend functionality every which way. The handy clip-on set-up allows quick switching of the main unit between basic black and five add-on wristband colours, or you can clip it wherever you please. It’s dustproof, splashproof, and charges via USB, with a battery rating of up to four days. Compatible with most Android 2.1+ phones. $149.99.
