Apple has started production of a thinner, more powerful version of its popular iPad tablet computers, according to unnamed sources cited by the Wall Street Journal on Tuesday.

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 4 smartphones, according to the Journal.

Cupertino, California-based Apple said in its latest earnings release that it sold nearly 15 million iPads in the eight months after the tablet computers were introduced in April of last year.
