Buy Portal 2 for PS3 and get it for PC too.

If I'm buying the console version, why would I want the PC version? I obviously prefer to play games on consoles, and I certainly don't need to beat the game same twice.

Can't really make sense of it from a business perspective either. I guess all the PC gamers can just buy the PS3 version now, providing false statistics to NPD, and putting a lot of used games on the market. Likewise, the PS3 gamers can sell the extra copy for less than the Steam price and keep the money far away from Valve.
