The Core is tiny. Thick as two sticks of gum, but twice as smart, this is Sony's renewed effort for wearables and it really couldn't look more different from the SmartWatch we saw in 2013. It's a different device to begin with: an activity tracker with no screen. Sony's still keeping it all pretty vague, but going on the details of the colorful, oddly appealing app, it's more life logger than health monitor. The idea Sony is chasing is to collect what you do in your life, your movement, your photos, music listened to and your social network goings-on, and collate them into a sort of automated journal -- a new LifeLogger app that will launch alongside the hardware.
You'll need to hook the Core up with your smartphone (through Bluetooth) to see what's happened activity-wise, and we've been told the battery should be good for up to five days on a single charge: it's tiny but there's no blinking lights or vibration to sap power. There's a micro-USB port for recharging, but the whole thing is also waterproof. Sony promises to reveal all the details at MWC next month, but we did get a glimpse at one of the places the Core will reside and, in true CES 2014 style, it's a wristband. We've got a quick video peek and a few more details after the break.
