HP has delayed the launch of its Android tablet device, All Things Digital reported on Thursday. The tablet had been scheduled for release at the end of the year. It’s believed HP is pushing back work on the Android device in order to focus on a tablet running webOS, the operating system it acquired when it purchased Palm earlier this year. This could be the second tablet HP has backed away from this year. Back in January, Microsoft CEO Steve Ballmer demonstrated the HP Slate, a tablet PC running Windows 7, at the Consumer Electronics Show in Las Vegas.
