Where is all this negativity coming from people? HP is a HUGE supporter of open source software. Goto
http://www.kernel.org and you will see HP is a proud sponsor of the Linux Kernel. The WebOS platform is another Linux distro created by Palm. The fact they want to show off their new acquisitions off so soon maybe a bit premature, however it shows that they are not planning on letting the IP just set on the shelf collecting dust. WebOS as well as Android (or ChromeOS) both show promise of being ported to platforms and formats to ditch the concepts of what we know as a modern operating system.
For the commenter who blames the WebOS for the downfall of Palm, this isn't true. WebOS was Palm's best chance of surviving. The lack of new and innovative products in many years is Palm's undoing. Sitting on IP like BeOS instead of using it, is Palm's undoing. Not keeping up with the Jones (aka RIM, Windows Mobile, Linux, ect) is Palm's undoing. WebOS was a great idea, just a little late to the market to compete.
Most likely you will NEVER see a version of the "Hurricane" with Windows 7. From my grapevine, the "Hurricane" platform will be ARM based to compete with MSI and Asus's offerings of tablets. There was talk in the shop about another netbook concept similar to the TX1200 and TM12 series notebooks running the latest Atoms with Optimus coming from HP.
