After all, Facebook has one of the most popular iPhone apps out there. Imagine what it could do with a unique, branded mobile platform that enables capabilities that haven't been seen before--at a bargain price, and without the stern oversight of Steve Jobs or need to interact with Google.

I really hope Zuckerberg is seriously considering it.

4. Open Source

Last but certainly not least is the option for HP or some other purchaser to open source WebOS. This, indeed, is actually my favorite option.

HP itself, or a purchaser of WebOS, could release the software as open source and thereby help to bring a whole new world of software, standards, and freedom to the market. The result could be even more disruptive than Android has been.
