The Chrome OS seems to be built for the net book community but they are looking to expand the OS into other markets. As of right now the OS is very hardware dependant. Google has a set list of compatible hardware meaning you may not be able to download the OS and just install it. Google is giving all of the code back to the open source community.  Here is a video that will explain more about the chrome OS.

Some of the main points from the webcast:

Chrome will launch in 2010

Under the hood:
-  No hard disks, only solid-state drives
-  Verified boot, meaning if the boot does not pass signature then it will reload.
-  Security: the OS does not trust any app
-  Read-only root file system (Better Security)
-  User data synced to the cloud. If your cloud goes down. O noooz
-  Automatic updates for the entire OS

Trends:
-  Net books have taken off in popularity
-  Web Browser are 90% of what people use PC’s for

Chrome OS:
- Instant boot (Under 7 Seconds)
- Every app is a web app no native apps like android
- All data is in the cloud
- Browser security model. Sandboxes Apps.
