Gadget Ogling: Budget Fitness Tracking, Focused Writing and Red-Hot Wearables

Gather around, friends, for another edition of the column that holds up just-announced gadgets to scrutiny, Gadget Dreams and Nightmares. In the stocking for our pre-holidays edition are a smartphone-controlled lock, an inexpensive fitness tracker, a red-hot wearable and much more. While I've looked before at smartphone-enabled door locks, Sony's take on the idea, the Qrio, stands out. Instead of having to remove existing locks to fit these devices, one need only place it over a door's current lock and attach it to the door.
