Over the past two years, the development of computers has matured significantly, and it's no longer a hot topic that everyone is overly focused on. Many small partners have shifted their attention to mobile phones. However, computers remain an essential tool in our daily lives. Xiao Bian wants to point out some of the useless designs that shouldn't even exist on such a crucial device. Some are unnecessary, others are redundant, and some are even harmful to your health. Let’s take a look at what they are! Top 5: CD/DVD Drive How many young people have used CDs in the past year? Now, fewer PCs come with optical drives, but many older cases still have 5.25-inch drives — mostly unused. CDs? They’re almost obsolete. On one hand, online videos satisfy most of our video needs, and downloading high-definition movies via the internet is much more convenient. Installing an operating system? Xiao Bian has shown you how to create a bootable USB drive countless times. For data sharing, USB drives and external hard drives are faster and more practical than discs. Moreover, over the years, Xiao Bian has always thought of CDs as a "fraud." Even lab-grade CDs can become unreadable after just a couple of years. The combination of performance, functionality, and storage capacity makes them unsuitable for today’s era. It’s time to remove these outdated components from future machines or simply eliminate the space they occupy. Top 4: N-Key Mouse Does high-end mean having dozens of keys? Many gaming mice advertise with multiple buttons, promising better performance. Xiao Bian was once into RTS games and knows how important control is. But do all those extra buttons really help? At least in Xiao Bian's experience, they don’t — especially when some keys are hard to reach. In Xiao Bian’s view, a five-button mouse is sufficient. Left, right, and middle click, plus forward and backward buttons, offer enough flexibility for most tasks. For complex macros, a dedicated keyboard is far more efficient than trying to manage everything through the mouse. Top 3: Single Interface Design Since Apple launched the MacBook, the trend of minimalistic laptop interfaces has taken off. Some models now have just one or two ports, which looks sleek but raises questions. Is it really practical? These devices force users to carry around a bunch of adapters and cables to connect different peripherals. That’s not only inconvenient but also adds extra costs for users. Simplification isn’t bad, but it shouldn’t come at the expense of usability. A balance between aesthetics and function is key. Top 2: Built-in Speakers and USB Ports on Monitors Xiao Bian must apologize first — he can’t stand built-in speakers on monitors. Why would a monitor need “speakers� Because HDMI can output both audio and video, but the sound quality is terrible. It’s absurd that users have to suffer for this. Why should they pay for poor audio quality? Additionally, many monitors add USB ports for convenience, allowing you to connect a keyboard, mouse, or flash drive. But why complicate things? A monitor should ideally have just one data cable (HDMI or DP) and a power cable. Adding USB ports only creates more clutter and confusion. Top 1: Light Pollution If the previous items were tolerable, light pollution is absolutely unbearable. According to Baidu Encyclopedia, light pollution is a new form of environmental pollution, including white light, artificial white light, and color light pollution. It threatens human health. Xiao Bian lists products that contribute to RGB glare: backlit keyboards, case lights, fan lights, motherboard LEDs, and memory strips. These flashy lights are not only distracting but also harmful to vision, especially when paired with dark backgrounds. This kind of design is purely for show and has no real functional benefit. Quality and usability should be the priority, not unnecessary lighting. These might not be the same useless designs you’ve encountered, but Xiao Bian hopes this list sparks some discussion.
