Technology is everywhere these days — even in your medicine cabinet. The Wall Street Journal's Digits blog reports AT&T is offering a service through products called GlowCaps that send data to the manufacturer every time a user opens the medicine bottle in hopes of reminding them to take their medication. A cool idea, but it won't come cheaply: $10 for each cap plus $15 a month for service that includes an AT&T mobile network connection.
