When the Metropolitan Transportation Authority promised that New York City's WiFi-packing buses would arrive sometime in the second or third quarter of this year, it was clearly being cautious -- the first wave of those buses is rolling out today. Visit Queens and you'll see seven internet-savvy people carriers roaming the streets, with a total of 75 in the borough this summer. That's still tiny next to the 2,042 planned buses for the entire city, but it'll be helpful if you just have to get your tablet online when you're in South Jamaica.
