SAN FRANCISCO (AP) -- Apple Inc. showed off new MacBook Pro laptops with longer battery lives, faster processors and lower prices.
Apple made the new 13-inch and 15-inch MacBook Pro laptops the introductory part of its developers' conference in San Francisco, where speculation swirled that a new iPhone would be unveiled later in the presentation.
The laptop with the 13-inch screen starts at $1,200, and the 15-inch model sells for $1,700 and up -- both $300 less than existing similar models.
The company also lowered the price on its ultra-thin MacBook Air to $1,500 from $1,800.
Apple's 17-inch MacBook Pro, which was unveiled in January, costs $2,500 and up.
Shares of Cupertino, Calif.-based Apple were down $4.27, nearly 3 percent, at $140.40 in afternoon trading.
