It looks like HP is planning on adding a new form factor to its list devices based on Palm’s webOS.

In a training video on its website, HP listed netbooks, slates and smartphones as a “friendly little product family” of devices that would all use its operating system.

The video touts the operating system’s strengths, as well as over-the-air updates and the devices’ ability to “talk” to each other.

The company’s consumer products chief Todd Bradley said in an August conference call with analysts that HP was looking to get into the tablet market.

“As we look at tablet sales and slate sales that was a big part of the reason we acquired Palm,” he said, according to a transcript of his comments provided by SeekingAlpha. “You’ll see us with a Microsoft product out in the near future, and a webOS-based product in early 2011.”

The training video did not provide a specific launch date for HP’s webOS-based netbooks or tablets, but the company has sent out invites for a Feb. 9 press event asking participants to “‘Think Big. Think Small. Think Beyond,” where it’s expected the company will debut new products.
