WebOS is a Linux kernel based assistance operating system, and developed by Palm mobile for its last generation of smartphones. The first WebOS device was the original Palm Pre, released by Sprint in the US in June 2009.

The webOS offered some visionary UI features, which collected lots of popularity. Unfortunately, the platform didn’t provide the tensity Palm needed on the smartphone market.

In 2010 HP procured Palm and later on in 2011 released a tablet using the OS – the HP TouchPad. After some reconstitution changes, it was decided that HP will no longer develop webOS and the TouchPad project was dishonored. Later on HP released an open source version of the OS called Open WebOS.
