Some people compares it with Linux, and see it as an UI addon with the Chrome browser, but they miss the point. Google Chrome OS is really a paradigm shift. The idea is that nothing (except a crypted cache) will be stored locally. Everything else will be stored in the cloud.
That means that if you switch from one notebook to another, you will get exactly the same thing and environment.
For example, there are discussions why Chrome OS only supports SSD, and not the old disk types. The reason is speed. And it will not be expensive as you will not need much storage.
Another questions is why only some selected platforms will be supported. Again, the idea is not that you should replace your OS at your current home computer. The idea is that the next generation notebooks, as well as smaller devices, will bring a new way to work.
