Google didn't do a good job at explaining the intended use of Chrome OS and many people wondered if Google's operating system is an alternative to Windows. The goal is to build "an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web".
Nice and brief article that can help to put the new Google OS in the right perspective. Briefly, this OS can't be seen as competitor to most used operating system: it simply lacks a lot of features to allow such kind of comparisons! Conversely, it came with a number of peculiarity that can be very interesting in selected fields, such as (just to say one) netbooks.
It may be taken as an excellent example of the intrinsic flexibility of linux, don't you think so?
