The service is accessible for free via Wifi-enabled computers, tablets, or smartphones and features free access to a bevy of selected video, textual, and audio content (i.e. selected books, videos, games, magazines, and music).
Highlights include: free access to the subscription editions of the New York Times, Wall Street Journal, and USA Today; exclusive iTune downloads; and free, unlimited access to Zagat restaurant reviews and ratings.
With all the added perks, the Starbucks Digital Network definitely encourages customers to come in and pull up a chair, whether any chairs will be available is the question, especially in high-traffic stores. I know that other popular coffee houses already have problems with too many people occupying seats to use free WiFi. My own local Starbucks stores are already pretty crowded, seating-wise.
