We bought a PC with Windows 8, about three months ago, it was released in October 2012.
So far... I have nothing but good things to say about Windows 8. It has a store app on the main screen... where you can download a lot of free aps, ranging from news, entertainment, etc. You can easily move the newly installed apps around on the main screen.
Also, there's a desktop app to click on, which takes you to your icons and wallpaper, just like Windows 7 and XP that you're already used to.
All in all, Windows 8 is great. I wouldn't want to go back to XP or Windows 7.
Here is a great video of Windows 8:
