Nah, T-Mobile is ubiquitous here in the states- they have Starbucks (which is on every 4th street corner it seems here in SoCal), Hyatt, Borders, FedEx/Kinkos (and some other chain I can't think of right now) as partners. Hell, even T-Mobile Retail (Cellphone) stores have it- I've been known to park outside one to check E-mail.
I can spend whole days outside my office space getting real billable work done (I have a small software business) thanks to their overwhelming presence.
