When I first strapped on the Microsoft Band a week ago, I felt like I’d been given new power over myself. The company’s first wrist-borne activity tracker packs 10 sensors into a discreet package, and to my hopeful eyes the wristable’s powerful specs added up to potential. I thought, this gadget might really get to know me, and inch me towards a better version of myself. Which is why it’s disappointing that the Band doesn’t meet that goal.
