Interesting article in NYTimes about a proposed smart phone app to call a taxi.
Apparently NYC is one of the few cities where you hail a cab on the street. Just go to the curb, raise your hand, and roaming Yellow Taxis come to you. And in central locations there are many taxis and in general it works well.
However, in other cities you have to call private dispatchers (like livery services, Dial 7, etc) who send cars to you, often cars in bad repair, and the system doesn't work well. therefore these apps were developed.
Unfortunately, like illegal vacation apartment rentals, these apps may be illegal in NYC. There is a lively debate ("Comments") about many people (usually non-Nyers or visitors) who think these apps are greater, and locals who think we don't need it in NY and it will change the taxi market to favor cellphone users, require pre-registration and preapproved credit card, waste eveyone's time, be an unnecessary middle-person. etc.
What do you think?
