Microsoft unveiled windows 8 few months ago. I am currently using Windows 8 Pro original version. I faced lots of problems starting from metro / modern UI. The metro / modern UI is not suitable for desktop PC from my experience. I also faced some irritating errors and ended up re installing the windows 8. Like wise, people are ready to downgrade from Windows 8 to windows 7 for $125 because windows 8 sucks. Here is the image shared by Michael Jurewitz
