Apple CEO Tim Cook took a trip to Bellevue, Washington last week to meet with Valve CEO Gabe Newell at Valve HQ. The reason for the meeting is a mystery – but it’s clear that Valve is doing everything it can pushing the Steam platform to Mac gamers.

Could Valve be looking into iOS development beyond the Steam app that they released? Is a partnership of some kind in the works? Does this all have something to do with the awesome rumors about Valve playing with hardware? Only time will tell.
