Most infrastructures are dictated by the government, which assures agreement to a single standard. When there is no standard, as in AM stereo or digital cellular options in the US, there is chaos. In the early days, technology dominates. All that matters is better, faster, cheaper, more powerful technology. In the middle stages, marketing dominates.
User experience can dominate, user experience and marketing.
As in soap and cereal. As in watches. The computer industry is now mature. The customers want convenience and value for their money. They want ease of use, emotional appeal.
