So you want to read about companies with no competitive advantages anywhere in the organization? Maybe some big firm that uses its marketshare to enforce a significant amount of revenue as opposed to better handling of operations, marketing, R&D, customer support, sales, etc?

Technology isn't the only comparative advantage.

Nor, is it necessarily the best option when maximizing comparative advantage over another firm.

Nor, is implementing new technology necessarily a comparative advantage, it could be a disadvantage (ie. if the technology fails either technically or on the business side)

It's often the most difficult or worst option because of the costs and risks involved.
