I've been a monthly customer of T-Mobile's hotspot service for a few years. I used the service almost exclusively at Starbucks stores. So, with the new announcement that AT&T and Starbucks will be offering two-hour chunks of use for free if you have a Starbucks card (the refillable type) as well as a $20 per month unlimited use option. It looks like I will no longer need the more-expensive T-Mobile account. The only time I've ever used it outside of Starbucks was at airport locations (Red Carpet Club), and I'm not flying as much as I used to (thank goodness).

You can't really beat free WiFi, and it's everywhere these days (except Starbucks), so this is a smart move in my mind.

From BetaNews:

While final pricing structures could change, some details have come out: the service will cost $3.99 for two hours of Internet access. But those customers who register and use their Starbucks card will receive two hours of free access per day. An unlimited plan is available for $19.99, which includes access to over 70,000 AT&T hotspots worldwide.

Existing T-Mobile HotSpot customers aren't being left out in the cold; thanks to an agreement with AT&T, they can continue to access the Wi-Fi at Starbucks without paying extra.
