One of the many, many wearables we saw at Mobile World Congress is now available for purchase, even if it is a little hard to find. Sony's Smartband SWR10, the company's answer to the Fitbit and similar devices, is now shipping from an Amazon reseller. We're not sure why one Amazon vendor seems to have it before everyone else, even before Sony's own store, but it's there if you want it. The price is $114.95, with Amazon Prime shipping notably absent.
The SWR10 is definitely a fitness tracker, not a smartwatch. Its waterproof build and one-button, no-display design means that notifications are limited to vibrations. Sony's hook is a "lifelogging" angle: in addition to tracking fitness activity and location, the SW10 paired with the Lifelog app will record how long you've slept, where you've travelled and by what method, what music you've listened to, and more. It's basically an opt-in Big Brother. The big Life Bookmark button allows users to "bookmark" moments, telling the band and the app that what's happening at that moment is of particular importance. The bracelet can also handle basic music controls.
Is all that worth more than a hundred bucks? I'm inclined to say no, but if you want one, more power to you. Other retailers like Expansys still have the Smartband listed as a pre-order, along with multi-colored swappable wristbands. Importantly, it looks like Sony's Lifelog app hasn't actually been published yet, so you may or may not be able to use the SWR10 even if you can get your hands on one.
