According to Apple Insider, Tim Cook was spotted at Valve this week. Of course you know that means the rumors are going to be swirling hot-and-heavy for now until the end of time that Apple is buying Valve, collaborating with Valve, or at least secret best friends with Valve. So we thought we'd get a head start on the rumor mill and list the most likely things Tim Cook was actually doing at the lauded game developer, so far up the west coast:

1. Slathering the Steam client in green felt.

2. Putting the finishing touches on a wearable computer / home console / robot that uses Apple hardware and Valve software.

3. Playing Half-Life 3 with Gabe Newell and having a blast.

Let the conjecture begin!
