Two weeks ago, you could walk by any of the thousands of Starbucks and see people typing away furiously at their MacBooks and MacBook Pros, many with iPhone in hand or on neck. It was a typical scene, no big deal. Last week, however, things changed in a big way when Apple and Starbucks struck a huge deal. Going forward, when you enter a Starbucks with your iPhone, iPod Touch or laptop, your device will automatically recognize the iTunes Wi-Fi Music Store using a high speed Wi-Fi wireless network. Starbucks customers will be able to preview millions of songs for free, including a new "Now Playing" service that displays the name of the song playing in the Starbucks store at that moment.
