Business Week had an interesting piece of how technology is changing ordering or flagging down a taxi.

“Ray Markovich started driving a taxi in Chicago three years ago after shuttering his struggling wireless phone store. Driving a cab wasn’t particularly gratifying or lucrative—he had to pay $400 a week just to lease his 2011 white Ford Escape. It was predictable if monotonous work.

Well, there’s nothing monotonous about it now. In June, Markovich, a thin, well-dressed man with short brown hair and spots of gray in his mustache and goatee, walked into the local office of Uber, the San Francisco-based taxi technology startup. Uber put him through an hour of orientation, gave him a free iPhone that carries its car dispatch app and some gear to mount it on the windshield, and sent him on his way.

Since then, Markovich has had to dodge flak from traditional cabbies who complain that they can no longer pick up riders in the city’s tonier neighborhoods, and he’s receiving a constant flood of e-mails from Uber itself, offering steep discounts on new cars and other perks to secure his loyalty. At the same time, he has increased his earnings by about 20 percent and says he’s simply evolving along with his customers. “No one under the age of 40 with a smartphone is going out and getting a cab anymore,” says Markovich. “I say if you can’t beat ’em, join ’em.”
