HP has revealed plans to include WebOS on all of its WIndows PCs in 2012. It is not a dual-boot scenario–more like some form of WebOS running on or within Windows to provide access to WebOS apps.
The move is similar to Apple’s launch of a Mac OS X app store and inclusion of iOS-style app functionality within the desktop OS. For HP, bundling WebOS with Windows may be a stepping stone to eventually offering pure WebOS PCs without Windows.
The trend is also interesting because eventually the distinction between desktop OS and mobile OS will be gone. Right now, we have WIndows and Mac OS X on PCs, and we have iOS, Android, WebOS, and Windows Phone 7 on mobile devices likes smartphones and tablets. But, over time the line between desktop and mobile will blur and fade away completely and we’ll end up with some sort of hybrid evolution combining the features of both platforms.
