Video of a Dell laptop running OS X?

Could this be video of that mythical Dell laptop running the developers' copy of OS X for Intel?

Maybe. It could also be a Dell laptop running PearPC, and emulating the most advanced operating system on the planet.

We all know it wouldn't be that hard to fake this, and with the Cult of Mac calling the leaked builds a hoax I'm thinking this isn't kosher.

What do you think, dear readers?
