While the open sourcing of webOS and the exit of HP from the tablet and phone market may not be good news for the continued existence of webOS as a separate entity, it does allow us to learn from webOS and integrate it's best features into other systems, such as Android.

And who knows? Maybe webOS will catch on. I know it made some design decisions that were superior to Android, in many ways. It was designed from the ground up for touch interfaces, whereas Android was designed initially for a keyboard + trackball interface. I think webOS will at least make Android stronger, even if it doesn't survive on its own.
