WebOS, the mobile operating system pioneered by Palm in 2009, and then absorbed by HP when it bought Palm a year later, will soon be a thing of the past. HP has announced that it will no longer support the OS and will discontinue operations for all devices currently using it, including the recently launched TouchPad.

The WebOS tablet was essentially dead on arrival, (Best Buy has since kindly asked HP to take some 200,000 unsold TouchPads back where they came from) and HP has decided to move in a new direction. It's not clear whether the company will develop a new OS or cozy up with a former competitor like Android or Windows Phone. 

Another one bites the dust.
