Google announced the future availability of its own OS, known as Google Chrome OS. Expected to be launched for H2 2010, this OS will be working on x86 and ARM CPUs. It is of course too early to further comment this announcement, even though it is quite obvious that Google's first target is the NetBook, as those hardware-limited notebooks will/have hard time to run any of the forthcoming new OS (Windows 7 or Snow Leopard).
