The downside to being wired at home is, well, finding a place for all the wires. But an upstart company called DeCorp promises to make things easier. Its innovation: FlatWire Ready wiring — electrical, audio, and cable wiring built into a ribbon no thicker than a business card. Demonstrated this year, FlatWire mounts right onto a wall and can be covered with paint or wallpaper, just like drywall tape. Available late this year; price not set.
