Don’t switch remotes every time you access a different home-theater component — let Logitech’s Harmony 676 do the legwork. Couch potatoes can easily program up to 15 peripherals (TV, CD/DVD player, ceiling fans, air-­conditioning units, etc.) into the clicker using an intuitive web-based interface. Better still, interchangeable faceplates give the gizmo added color, so it won’t disrupt your nightly routine by inconspicuously sinking into the sofa. $200. www.logitech.com/harmony
