When a person buys computers, electronics and office supplies, they are going to have to decide if they are going to buy something that is of high quality, but that may be a little bit expensive or if they are going to buy something that is of less quality and cheaper. Many people decide to put out extra money and buy something that will last a long time. For example, they may invest in membrane keyboards. If the keyboards end up having problems in the future, they will send them in to be repaired. They know that these keyboards are of the highest quality and it is best to use them for as long as possible.
