    However, a usability rating system clashes with one of the cardinal points of usability itself: Different users have different needs. In other words, usability isn’t as cut and dry as the number of calories in our potato chips.

    Perhaps we could create a usability rating system based on objective qualities related to usability, such as page load time, average clicks it takes to perform a user-action, background/foreground color contrast to measure readability, and so forth. But that type of rating system will only be able to tell a small portion of the entire usability story of a product.

    Feature Count and Price is Easier to Use

    I’ve found myself comparing the features and prices of two or more products on e-commerce sites simply by opening each option in their own browser tab and then just tabbing back and forth between them.

    When we are comparison shopping, we can easily count and evaluate features and prices, and then come to a quick conclusion.

    The same applies to brick-and-mortar stores, where we can actually see and touch the products we are considering. In stores, feature sheets and salespeople will never miss the opportunity to remind you that if your TV isn’t able to record five TV shows at the same time, you will never achieve happiness in life. And — surprise — the "slightly more expensive" TV right over there has it all. See? It says so right here in the feature sheet.
