@danluu I personally can speak about home appliances and tools. In both cases, poor quality ones cause waste of time, energy (less energy efficient), potentially materials (in case of tools), endangering the operator (think eg, of dull knives vs. sharp ones), and accummulating frustration.
Another example is computers; a Mac Mini we use as a home storage server is 12 years old; and we have only just recently got rid of a Mac Pro that was almost that old.
