Why do they charge the $2/hour dedicated fee for the CC2.8xlarge? Isn't that size already a dedicated instance if you just use it as an on-demand instance? You get 32 virtual cores which makes sense for a dedicated instance, since you get 16 physical cores (2x8) and the hyper-threading makes 32 virtual cores.

"CC2 and CR1 Instances are backed by 2 x Intel Xeon E5-2670 processors, eight-cores with hyperthreading"

Am I missing anything or is there a benefit to doing a dedicated cc2.8xlarge instance? Compliance maybe?
