At first blush, Starbucks' decision to drop T-Mobile and use AT&T to provide in-store Wi-Fi access may look like just another inside-business choice. A closer look, however, shows that there are at least six ways this decision could change the way many of us are mobile.

As a practical matter, the transition to AT&T means that anybody with a Starbucks card, which provides in-store credit, will get two hours of free Wi-Fi access a day. Currently, all Starbucks customers using T-Mobile's Wi-Fi network users must pay for access.

But free access is just the beginning. Here are six changes that have been created -- or at least clarified -- by the Starbucks-AT&T arrangement and what those changes will mean for users.

1. More free Wi-Fi

Coffee and Wi-Fi have always been sold separately in Starbucks. However, that model isn't working for Starbucks anymore.

Now, Starbucks "will be using Wi-Fi to sell more of their core products," said Derek Kerton, principal of The Kerton Group, a telecommunications consulting firm. "Other coffee shops use (free or cheap) Wi-Fi to get people into the store and Starbucks felt they were losing business."

Dan Lowden agreed that free-Wi-Fi benefits both customers and Starbucks. Lowden is vice president of marketing and business development for Wayport, which is the behind-the-scenes provider of the AT&T-branded Wi-Fi service that will be in Starbucks stores.

"It gives customers more value and that makes them more sticky," Lowden said. "Sticky" refers to customers who spend more and come back more often. He said Wayport, which also provides Wi-Fi in locations such as McDonald's restaurants, has run frequent surveys that confirm that fact.

The bottom line: Expect to see even more free hotspots at a greater variety of venues now that Starbucks has taken the plunge

2. More and better bundles

If this deal is a marketing win for Starbucks, it's also a big win for AT&T, even though the telecom supplier probably won't make much money directly from Wi-Fi.

"Is AT&T trying to make money on Wi-Fi hotspots?" asked Kerton. "No. Like Starbucks, they want to use it to sell their key products." And that, Kerton and others noted, means free or cheap Wi-Fi will increasingly be part of service bundles offered to customers.
