With WebOS headed for HP's PC portfolio, what happens to Windows?

As HP's WebOS event in San Francisco was coming to a close, executives came back on stage to recap all of the features that had been showcased on-stage and circled around to a comment that was made at the top of the event: These products are only the first of many in the WebOS portfolio.

And then came the quick mention that WebOS, an operating system that the company said is rugged enough for multiple devices, would also soon be popping up on HP's personal computers.

My first thought: What about Microsoft Windows?

One of my biggest criticisms of Microsoft has been the way it has rested on its cash-cow products, including Windows and Office, but has been slow to adapt for other form factors, such as tablets. Now, you have one of the biggest sellers of personal computers in the world - Windows-based computers, no less - talking about the excitement of building its multi-device operating system into personal computers as another WebOS "connected" device.

During the demos today, the company played up the seamless connections between the WebOS tablet, smartphones and even printers. It only makes sense that PCs would be in the mix, as well. And with the push to build a WebOS ecosystem sooner, rather than later, I imagine it won't take much time until WebOS becomes the primary OS on HP's personal computer lineup.

The mention was almost an afterthought and executives didn't say much beyond the announcement itself. But the message was loud and clear - and I can't help but think that it was so loud that it sent shockwaves through some glass offices some 800 miles away in Redmond, Washington.
