given the size of the storage I need, the price for the retina laptop is simply far to high for what I value in the package. its nice but insultingly poor value for money. As for the other models they are selling, they are not really anything special and don't offer me more than what I would get from other manufactures. With the cases being larger, I would also expect to have less thermal problems running at 100% CPU in an environment at 30-33C ambant.
