#4 Open WebOS

Open Web OS is a mobile operating system based on a Linux kernel, initially developed by Palm, which was later acquired by Hewlett-Packard and then LG Electronics.

Back in January 2009, Palm stole the show at CES by showcasing its brand new and surprisingly good-looking mobile operating system called webOS. But the Palm Pre and later models failed to catch the attention of potential buyers, leaving the company in a bad shape.

Various versions of WebOS have been featured on several devices, including Pre, Pixi, and Veer phones and the HP TouchPad tablet. HP made the platform open source, and it became Open WebOS, but Palm kept it as a walled OS till then.

Though LG said that it is planning to include the OS in its smart TV range of devices and other consumer electronics, but there’s possibility of eventually producing a phone or other mobile devices that run webOS.
