Windows 8 is it worth $40?

In Recent news It has been reported that Windows 8 upgrade will cost $39.99 going along with the last review does this make it worth the price?  The answer is it depends.  I still hold to the fact that Windows 7 is a much more functional operating system as of right now.  The fact that Windows 8 is basically 2 operating systems in one body, makes it challenging to use and will lead to frustration by those of us who teach others how to use computers and those of us who need to learn the new OS.  so my suggestion is unless you are a gamer, or need to use software that is proprietary through windows, go with one of Google's operating systems (Android or Chrome OS) or Keep your Windows 7 installation for a couple of years before upgrading.
