Most enterprises work on a combination of price per TB and price per IOP - when you use this appraoch SSDs are starting to look very attractive.
Also, prices are partly driven by volumes - once SSD volume starts to overtake HDD, princes will start to drop significantly and spinning rust will very quickly be consigned to the same shelf as betamax i.e. a great technology and still in use for some niche edge cases but ultimately doomed to disappear.
