The Apple iPad 2 was greeted by crowds during its debut in China on Friday morning, according to AppleInsider. Customers began lining up at about 5pm local time on Thursday, and there were hundreds of people in line by the time the store opened. Those who waited in line were allowed to leave to take one hour breaks, but anyone who spent longer was sent to the back of the queue. Scalpers also reportedly took to the streets offering the device at a relatively small markup. Chinese customers appeared to prefer the white iPad 2 over the black one, according to AppleInsider. We saw similar crowds during the U.S. debut at the New York City 5th Avenue Apple Store, where customers also started waiting in line up to 24-hours ahead of time for the device. Apple has yet to disclose its sales of the iPad 2 specifically, although it did sell 4.69 million units during the second quarter, down from the 7.33 million units it sold the quarter prior.
