Engadget has gone and gotten itself rendered images of HP’s unannounced 7-inch and 9-inch webOS tablets. The site’s source indicates that the smaller and larger tablets bear the code names Opal and Topaz respectively. The images indicate that both devices will have a front-facing camera and a micro-USB charging port; the devices also appear to be buttonless with the bottom bezel functioning as a gesture area. Look for the Opal to launch in September at AT&T, Best Buy, Verizon, Amazon, and host of others. Your friends at BGR will be at Palm’s mysterious media event February 9th in San Francisco. Hopefully, we’ll find out more about these two attractive tablets then!
