I'm laughing my ass off too. I am the proud owner of a PowerBook G4 and wouldn't have anything else, but this was hilarious.
By the way, my Mac played the video all the way through and I was thoroughly impressed. Was that Shaggy's girlfriend at the end....or Shaggy?
I'm sorry for poking fun at you Shaggy, I don't even know you but you seem to be the target from what Adam says

Look forward to meeting you. BTW, I'm not as big a prick as I seem. Tim, Adam, NO COMMENT!
