Windows 8 isn't even really available yet, but you can already play Pinball FX2on it. That's what we would call being "on the ball" ... if we were interested in terrible puns, which of course we aren't.
Windows 8 is available today in a consumer preview build, and Zen Studios' pinball game is included in the download, with the "Sorcerer's Lair" table. Of course, more tables will be sold as DLC. It's only fitting that this version of Windows, which touts some kind of Xbox Live functionality, will include one of Xbox Live's most popular games. To put it another way: free pinball!
