Apple has started production of a thinner, more powerful version of its popular iPad tablet computers, according to the Wall Street Journal. The second-generation iPad will have more memory and a front-facing camera for capabilities such as a Face Time video-conferencing feature on Apple iPhone 4. Cupertino, California-based Apple said that it sold nearly 15 million iPads in the eight months after the tablet computers were introduced in April of last year. I’m sure my father will be ALL over it.
