There have been plans since last year about converting public phone booths (was it AT&T?) to hot spots. Fastcompany now has a first review:

"Here's the lowdown: Internet speed and ease of use get high marks. I was able to sail to Google, Yahoo, and the New York Times with ease. I even went back to make sure my Yahoo and NYT passwords hadn't been saved once I left the sites. Great, so I know the thing's not storing any private information even when I accidentally asked it to.

bottom line: Lots of novelty, little use. Unless, of course, you need to make a good old-fashioned phone call."
