Apple is Most Valuable company of USA 2012

2012 Apple passes Exxon as most valuable US company

A customer, right, tries on the Apple Inc.'s iPad 2 tablet computer at a shop in Hong Kong Friday, April 29, 2011. The iPad 2 went on sale in Hong Kong, South Korea, Singapore and eight more countries on Friday.
The milestone occurred shortly before 2 p.m. Tuesday.
Apple Inc.'s stock gained 3.4 percent to $365.10 Tuesday afternoon, bringing the iPhone and iPad maker's market capitalization to about $338 billion.
Exxon Mobil Corp. shares, meanwhile, were trading at $69.23, down 1.4 percent. That gives the oil company a market cap of $337 billion.
Other big-name corporations, such as Wal-Mart Stores Inc. and General Electric Co., don't even come close.
Exxon, which set a record in 2008 for the highest quarterly earnings by any company, has limited growth prospects. Its growth is driven by oil prices and discovering new oil.
By contrast, Apple has been on a roll with the soaring popularity of its iPad tablet computer and strong sales of the iPhone. Apple's growth is limited only by innovation. Investors expect it to grow as long as it keeps making products that people want. So investors are betting on Apple's stock even though it currently makes less money than Exxon.
In its latest quarterly report, Apple said stronger iPhone and iPad sales helped more than double its net income to $7.31 billion and grow revenue by 82 percent to $28.6 billion.
Exxon Mobil, meanwhile, posted a 41 percent increase in its second-quarter earnings to $10.68 billion, the largest since it set a record of $14.8 billion in the third quarter of 2008. Its revenue grew 36 percent to $125.5 billion.
Apple, which is based in Cupertino, Calif., has a higher price-to-earnings ratio than Exxon Mobil, but not by much. They are both lower than that of the average of the S&P 500 index.
International companies that vie for the most valuable spot include PetroChina Co., the publicly traded unit of China's biggest oil and gas company, and Petrobras, Brazil's state-controlled energy company.
In the U.S., Exxon and General Electric had been trading off the No. 1 and No. 2 spots until Microsoft Corp. surpassed them both in early 1999, at the height of the dot-com boom. By 2000, though, GE was No. 1 once again. According to data from FactSet, the three were close over the next five years, though Apple was ascending quickly.
Exxon Mobil, which is based in Irving, Texas, took the top spot in 2005 and remained there until Tuesday.
Apple surpassed Microsoft in market cap last year.

A pictures of: Apple Mac OS X

The 'Cheetah', or Mac OS X version 10.0, was the first of Apple's big cat-themed versions of Mac OS X. Released in 2001, the new operating system marked a strong deviation from the Classic Mac OS with a completely new code base, changing the style of the desktop as well as the system of memory management. Although reviews were not quite as good as one would expect (users complained of missing features and issues with its performance) 'Cheetah' was noteworthy for its overall stability as an operating system. Unlike all later releases of Mac OS X, the cat code-name name was not used in promoting it.

iOS of Apple is Secure then Android of Google

Apple iOS beats Google Android on security, says research

Apple’s iOS mobile operating system is overall more secure against hackers and other online threats than its main rival, Google’s Android, according to research.

Worlf-Techtimes

Android Marketplace is more open than the iOS App Store

It is more resistant to three out of five types of threats including malware and data loss, the security firm Symantec said. On the other two categories, web-based attacks and social engineering attacks, the two operating systems came out even.

The security features of Apple’s software, which powers the iPhone, iPad and iPod Touch, are also better implemented than those of Android, Symantec said.

Measures including access control, encryption and the provenance of applications are all stronger in iOS, the research found. It said Android is better at isolating security problems when they do emerge, however.

Many of Android’s security problems stem from Google’s open approach to apps. While iOS developers pay to register with Apple, which checks and approves their work before it goes on sale in the App Store, Android developers do not face the same barriers.

“Google does not appear to perform a rigorous security analysis of applications posted to its Android Marketplace,” Symantec said.

“This means that malware authors can distribute their apps through this distribution channel with less likelihood of being discovered.”

The result has been that hackers have sought to take control of Android devices with rogue apps. In February criminals released apps that stole personal details from hundreds of thousands of users by impersonating 58 legitimate apps on Marketplace. Google has since patched the vulnerability they exploited in Android 2.3.
Meanwhile, the research said that while many more vulnerabilities have been discovered in iOS than in Android - more than 200 versus 18 - no malware that exploits them has ever been detected.
“While [Apple’s] vetting approach is not foolproof, and almost certainly can be circumvented by a determined attacker, it has thus far proved a deterrent against malware attacks data loss attacks, data integrity attacks and denial of service attacks,” Symantec said.
The finding does not apply to devices that have been jailbroken to allow them to run unauthorised apps. In November 2009 an Australian hacker released a self-replicating iOS virus that replaced the home screen with a picture of Rick Astley, the 1980s pop star.
While Apple's approach came out as more secure than Google's, Symantec said that using a smartphone or tablet running either operating system was less risky than using a PC.
"These platforms have been designed from the ground up to be more secure - they raise the bar," it said.
RIM's BlackBerry is widely considered the most secure smartphone platform because it can be tightly controlled by corporate IT departments and has received government accreditation.

Nokia get $608 from Apple

Apple agrees to pay Nokia patent licensing fees

Apple has agreed to license wireless phone patents owned by Nokia that sparked a long-running legal dispute between the two companies.
The deal will settle all patent litigation between Nokia and Apple, and the two will withdraw their respective complaints filed earlier with the U.S. International Trade Commission. In addition, Apple will pay Nokia an undisclosed one-time fee and on-going royalties, Nokia said today.
"We are very pleased to have Apple join the growing number of Nokia licensees," Stephen Elop, president and chief executive officer of Nokia, said in a statement. "This settlement demonstrates Nokia's industry leading patent portfolio and enables us to focus on further licensing opportunities in the mobile communications market."
Apple representatives did not immediately respond to a request for comment.
The legal skirmishing began in October 2009 when Nokia sued Apple in over 10 wireless handset patents the Finnish phone maker said it owned. The 10 patents, which Apple reportedly refused to license, relate to making phones able to run on GSM, 3G, and Wi-Fi networks. They include patents on wireless data, speech coding, security, and encryption, according to Nokia.
Apple filed a countersuit in December 2009, charging Nokia with infringing 13 Apple patents related to the iPhone. In its suit, Apple denied Nokia's claims of copyright violations and said that the licenses for which Nokia was seeking payment from Apple were "unfair, unreasonable, and discriminatory" and "non-essential" to the iPhone.
The dispute escalated later that month when Nokia lodged a complaint with the U.S. International Trade Commission, accusing Apple of infringing seven Nokia patents "in virtually all of its mobile phones, portable music players, and computers."
A Delaware court put the lawsuits on hold in March 2010, pending the trade commission's decisions on the matter. Apple then took its fight to the U.K. in September 2010, accusing Nokia of infringing on 9 patents it owned.
However, a judge with the U.S. International Trade Commission ruled in March that Apple was not in violation of five of Nokia's patents.
Update, June 14 at 11:41 a.m. PT: Deutsche Bank analyst Kai Korschelt estimates that Nokia will likely be getting something on the order of $608 million from Apple as a result of the settlement.
