Full of energy, Jobs attacked rival companies and ridiculed competing tablets, in defiance of the information appeared in some tabloids that claimed he was seriously ill.

iPad 2 will enter the U.S. market on March 11 and will make its appearance in other countries on 25 and 26 March.
The tablet has a 1GHz Apple A5 dual core processor and the graphic performances are up to nine times better than the first version of the iPad, according to Engadget.
Scheme prices start at $ 499 for the basic version with 16 GB of storage and limited connectivity to WiFi, and reaches 829 dollars for the version with WiFi, 3G and 64 GB of space.

Apple has sold nearly 15 million iPads after its launch in April 2010, three times more than some analysts estimated. The company might sell another 30 million this year, generating revenues of nearly 20 billion dollars, despite the emergence of numerous competitors such as Samsung, Motorola, Hewlett-Packard, Dell or Research In Motion.
As on the smartphone market, Apple’s main rival will likely be Google’s Android operating system, built by many gadgets manufacturers.
