I'm blogging from a Quizno's in Westwood. No, the world's most disorganized sandwich chain hasn't installed wi-fi. But the place is three doors down from Starbucks, and if you sit in the back you can use the Starbucks T-Mobile network. Since I needed lunch and prefer Diet Coke to coffee, that's what I'm doing. And since I have a lot of travel coming up this fall, I've taken the plunge, signing up for a T-Mobile wi-fi subscription--good not just in Starbucks but in Borders and American Airlines' Admirals Clubs, both of which I frequent, well, frequently. I'm too addicted to broadband to spend months of travel relying on dial-up Earthlink access.
