Steve Jobs unveils Apple iPad 2

Watch this video to know what is in store for those who are eagerly waiting for the release of Apple iPad 2.

Apple CEO Steve Jobs, who was diagnosed with pancreatic cancer in 2004, though on medical leave since January 2011, presented the improved version of iPad and said, “We have been working on this product for a while and I just didn’t want to miss today.”

So, Jobs showed off the second generation of the iPad tablet computer on March 2, at an event in San Francisco. The new iPad which is scheduled for shipping on March 11 comes with two models in terms of color: the white iPad2, and the black iPad 2. Jobs said that Apple will be shipping out the white model on day one of starting shipping of the product.

Also, Jobs said the new version of iPad is 33% thinner than its predecessor, thinner than iPhone 4, and it weighs less than iPad 1. He said iPad 2 is also much faster as it is equipped with what he called the A5 processor, a new chip with a dual core processor. The machine is twice as faster on CPU performance and 9 times faster on graphics performance, Jobs said.

Also iPad 2 comes with two cameras to make video conferencing more convenient: a built-in rear camera and a front-facing camera. The other features included can be a video editing package iMovie and a music making program.

The all new design iPad 2 will be priced at the same old price of iPad 1, starting at $499 (£305). The gadget will have 10 hours battery life, and over one month standby, Steve Jobs said.

What Steve Jobs calls ‘the dramatically improved product’ will go on sale in the U.S. on 11 March, and later on 25 March it will be available in 26 other countries including the UK.

According to industry analysts, Apple iPads accounted for 95% of tablet computer sales until September 2010, but the sales declined to 75% by the end of 2010. The fall in sales is due to new tablet devices that are based on Android operating system, Google’s open-source product.

Microsoft Windows 7 and HP’s WebOS are the other platforms that are competing with Apple iPads. According to reports, a lot more products are expected to give tough competition to Apple’s tablet PC throughout 2011, as over 80 new devices have already appeared in the market.

This supercomputer is named Columbia Supercomputer in honor of the crew of the ill-fated Space Shuttle Columbia that disintegrated over Texas on February 1, 2003. The disaster resulted in the death of all the seven crew – Commander: Rick D. Husband, Pilot: William C. McCool, Payload Commander: Michael P. Anderson (also in charge of science mission), Payload Specialist: Ilan Ramon (an Israeli Air Force colonel, also the first Israeli astronaut), Mission Specialist: Kalpana Chawla (an India-born aerospace engineer on her second space mission), Mission Specialist: David M. Brown, and Mission Specialist: Laurel Clark.

The Columbia Supercomputer was specially built for NASA by Silicon Graphics. The main purpose for which it was built was to “esimulate the violent collision and merger of spiral galaxies that lead to the formation of elliptical galaxies”. The supercomputer is connected to the NASA Research and Engineering Network. In 2004 it was installed at the NASA Advanced Supercomputing facility at Ames Research Center (ARC) located at Moffett Field in California’s Silicon Valley.
