This MIGHT happen faster than any of your think.
In the paper in the last few days, Fry's had a blue ray drive for the PC that was $ 199 !
This has NOTHING to do with the price of drives.
Apple has always charged waaay too much for their stuff.
Completely subjective statement.
Apple couldn't care less about the price of drives. Apple cares about the licensing and the fact that Blu-ray can modify the operating system on which it is running. Apple will never allow that.
