The Band looks and feels a bit like a prototype, a relatively unadorned wristband with a clever sliding clasp (so you can change how it fits without taking it off) and a 1.4-inch, 320 x 106 display on the front. There are two buttons below the display: one for waking the device, and the "action button," which you use to scroll through data or start and end a workout. I quickly paired it to my iPhone 6 via Bluetooth, downloaded the beautifully minimalist Microsoft Health app, and was off. It automatically started tracking my steps and heart rate, funneling the data back to the app every time I hit sync.
THE HARDWARE NEEDS SOME WORK, BUT THE SOFTWARE IS ALREADY SOLID
Throughout it all, notifications were coming in — text messages, emails, calls — and vibrating my wrist powerfully enough that there's no way I'm going to miss it. I couldn't do much other than dismiss them, since the Band doesn't connect to Siri the way it does Cortana on Windows Phone, but leaving my phone across the room is certainly nice.
Now for a nap. Let's see how that goes.
