Sept. 28 (Bloomberg) -- Apple Inc., which sold more than 3 million iPads in the first 80 days after the tablet’s debut, may introduce a new version in the second quarter of 2011, according to analysts at Goldman Sachs Group Inc.

The new iPad with a 9.7 inch display may be thinner and lighter, with a built-in camera and mini USB port, analysts Henry King in Hong Kong and Kevin Lu in Taipei said in yesterday’s report. Hon Hai Precision Industry Co., the world’s largest contract maker of electronics, will likely be the supplier, they wrote.

The iPad touchscreen computer has become one of the Cupertino, California-based company’s top-selling products in its first year on the market. The tablet faces competition from similar products by Hewlett-Packard Co., Samsung Electronics Co. and Research In Motion Ltd., which unveiled a 7-inch device yesterday.

Sales of such tablet computers could reach 16 million units this year and 35 million in 2011, according to Goldman Sachs.

The creation of a smaller 7-inch version of the iPad hasn’t been finalized, the analysts said. Natalie Kerris, a spokeswoman for Apple, declined to comment.

Apple fell $4.30, or 1.5 percent, to $286.86 in Nasdaq Stock Market trading at 4:30 p.m. New York time. The shares have risen 36 percent this year.

Last quarter, iPads accounted for $2.17 billion, or 12 percent, of Apple’s overall sales, more than the nine-year-old iPod. The iPad went on sale in April.
