Jon Rubinstein, the former chief executive officer of Palm and a former high-ranking exec at Apple, became a former exec from Hewlett-Packard after he left the company this week. His departure breaks yet another major link between HP and webOS, a mobile platform that the company got from Palm and which it essentially dumped by deciding to make the webOS an open-source.

“I am going to take a well deserved break after four and a half years of developing webOS,” said Mr. Rubinstein in a brief interview with AllThingsD web-site.

Mr. Rubinstein is known as one of the creators of Apple iPod, the most popular product from Apple ever. He also served as chief executive officer of Palm before the company was acquired by HP for $1.2 billion back in early 2010 only to dump it in summer, 2011, after a weak start of TouchPad slate sales.

The resignation of Jon Rubinstein from HP is barely surprising since HP  no longer develops webOS and even decided to cancel all of devices that were originally sold under Palm brand. While the firm has plans to make webOS-based tablet in 2013, those plans are not too solid and currently are not public. In general, the departure of Mr. Rubinstein marks another rather evident situation: HP no longer wants to be in the business of mobile devices.

HP has confirmed leave of Jon Rubinstein.
