NEW YORK: Apple appears to be making less of a profit from each new iPad than it did when it launched the previous model a year ago, according to a research firm's analysis.   IHS iSuppli took apart a new iPad on Friday, the day the device went on sale in the U.S. and nine other countries, and found that the components are more expensive than those of the iPad 2.   The third iPad comes in several versions starting at $499, the same price as the iPad 2 at launch.   Apple has priced all three generations of the tablet aggressively, making it hard for competitors to match its features at the same price. It makes less from each iPad than from each iPhone.   As a whole, Apple is wildly profitable, earning $33 billion in net income on $81 billion in revenue in the last calendar year.   ISuppli said a new iPad with 32 gigabytes of RAM and a cellular modem, which costs $729 in stores, costs $364.35 to manufacture. That's 9 percent more than the $335 it cost to make the corresponding iPad 2 a year ago, when it came out.   The corresponding version of the first iPad cost about $276 to make in 2010, according to iSuppli's estimate.   ...
