I have heard negative remarks about the new Windows OS. I am happy with my Windows XP and Windows 7 systems. One is desktop and other is laptop. I do not think that unless our apps need the upgraded Windows version, it should be there! There are already so many versions of Windows since last few years, and most have become obsolete in just few years or even months. I would really see how the new OS functions over at least 2 years, and then will think of upgrading it, and that too if it suits my work.
