After a long wait, HP today announced that it will finally debut its first tablet based on the webOS mobile operating system in the United States on July 1.

Initially, the HP TouchPad will only be available with Wi-Fi connectivity. However, later this summer, HP stated, it will release a connected version of the tablet through AT&T.

HP bought the rights to webOS last year when it acquired Palm, the creator of the mobile operating system. Under Palm, webOS saw mediocre success as a smartphone operating system. However, many industry observers and pundits have said the OS could be ideal for media tablets.

"What makes HP TouchPad a compelling alternative to competing products is webOS," said Jon Rubinstein, senior vice president and general manager of HP's Palm Global Business Unit. "The platform's unmatched features and flexibility will continue to differentiate HP products from the rest of the market for both personal and professional use."

HP also stated the TouchPad would be available with several tablet accessories, including a charging dock, a wireless keyboard and a case, each of which are sold separately.

According to Gartner, webOS will represent 4 percent of the global media tablet market this year, trailing behind Android, MeeGo and the market leading iOS from Apple.
