Valve finally confirmed today that they will be bringing Steam over to the Mac. This announcement had been expected following the teaser ads they had out last week. Some very cool points made in the announcement are people who already own a game for the PC can re-download it for free for the Mac. Another note is that they are considering it to be a tier-1 platform so everyone can expect releases the same day as their PC and Xbox 360 counterparts. The first simultaneous release is going to be Portal 2! It seems like Apple is finally going to be able to rid themselves of the stereotype that in order to play games you have to have a PC.
