Probably the greatest downside of standardization for consumers is lack of variety. There is no guarantee that the chosen standard will meet all consumers' needs or even that the standard is the best available option.  Another downside is that if a standard is agreed upon before products are available in the market, then consumers are deprived of the penetration pricing that often results when rivals are competing to rapidly increase market share in an attempt to increase the likelihood that their product will become the standard.  It is also possible that a consumer will choose a product based upon a standard that fails to become dominant.  In this case, the consumer will have spent resources on a product that is ultimately less useful to him or her as the result of the standardization process.
