Those of us that are old enough remember the slogan for the original iPod. But instead of a thousand songs, the Kangaroo Portable PC puts a full-blown computer in your pocket. Powered by an Intel Atom processor, it runs 64-bit Windows 10, and can be hooked up to a traditional monitor and keyboard, a TV, or even an iPad or other tablet. It has 32GB of internal storage, a fingerprint reader for security, a built-in rechargeable battery that gives you up to four hours of casual use, a micro USB port, and an external dock that adds HDMI, USB 3.0, and USB 2.0 ports for desktop use.
Not all exercise is created equal, but you'd be hard-pressed to tell by the readouts on most monitors. The Garmin Vivosmart HR Activity Tracker uses an integrated barometric altimeter and heart rate monitor to give you credit for activity performed at higher altitudes, as well as exercise that gets your heart pumping. Its daylight-readable display is always on, yet it can run up to five days on a single charge, while doing all the expected fitness tracker stuff like displaying notifications, tracking steps, and giving you a nudge when you've been sitting for too long.
