sometime we pay more on something for.
Reliability, we want to know that the things we buy can use by consistency.
Availability, we want to make sure that we can use that on time, with out searching.
Effectively, we want to make sure the output is at maximum by the same input.
Sensuality, we want the good design products, not just only function.
What if the product is outdated, cannot be used, ugly, and non stable. why some people still want to use that?
i don’t know, it never make sense at all.
