OUR COMPUTERS, our phones, our tablets, our watches—all are devices of wonder that can make our lives easier. Until they don’t. There’s no getting around it: These are complicated pieces of technology that can sometimes create as much frustration as benefit.

They considered a number of common issues people share with their technology and provided their best tips and suggestions for addressing them.
