5 designs that haven't changed over the years

Here are five tech products whose designs have remained unchanged for decades and are likely to continue to do so for the foreseeable future.

Keyboard layout

Keyboards come in two types of layouts: functional and physical. Functional layout is simply the arrangement of the keys, such as a QWERTY keyboard. Physical layout is the overall layout of the keyboard, including not only the letter and number keys but also Caps Lock, Shift, etc.

The keyboard has not changed much since then.

In the PC world, the modern keyboard has remained essentially unchanged at its core. If you sat in front of an IBM PC from the 1980s, you would know more or less how to use its keyboard. Even the virtual keyboard on a touchscreen takes its design cues from a computer keyboard.

Ethernet connector

The Ethernet connector is inspired by the world of telephones, which is why it looks like a telephone line connector. The telephone connector is called RJ11, while the Ethernet connector is called RJ45.

Despite the continued advancements in Ethernet speeds, the actual connector itself has remained largely unchanged and is largely backward compatible. This means you’ll find RJ45 connectors on everything from 10Mbps 10BASE-T cables from the early 1990s to modern Type 8 Ethernet cables that can handle 40Gbps, 4,000 times faster.

Apple white charger

If you own an Apple laptop, does its charger look dated? In fact, it’s a design that dates back more than 20 years. Until the late 1990s, Apple’s laptop chargers differed from those of other manufacturers only by having a slot to wrap the cord around. The company briefly experimented with the “puck” or “yoyo” style from 1999 to 2001. It was an instantly recognizable circular charger.

Apple remains loyal to the white charger

But in January 2001, the PowerBook G4 debuted with a “white brick” charger with a non-detachable cord from the barrel connector. The second-generation iBook G3, announced in May of that year, used a similar charger. In October, the first iPod was announced with a white charger with a FireWire port.

Since then, at least a dozen other models have been produced, with USB-A ports for iPods, iPhones, and iPads; MagSafe 1 for MacBooks from 2006 to 2012; MacSafe 2 from 2013 to 2015; and USB-C. There’s even a 35W dual-port USB-C adapter that ships with the 15-inch M2 MacBook Air in some markets.

What all of these chargers have in common is that they're compatible with the "duckhead" plug that AirPort Express routers use. You could literally take the cord from a 2001 PowerBook G4 and plug it into the charger on a MacBook Pro M3 and it would work.

DualShock/DualSense Controller

While the original controller sold alongside the PlayStation in the mid-1990s lacked the dual analog sticks we see today, it wasn't long before Sony created the iconic design with the Dual Analog controller and later the DualShock.

ThinkPad Trackpoint

One of the ThinkPad's most iconic features, the TrackPoint, has been around since the first models in 1992. It's the little red circle between the G, H, and B keys.

TrackPoint is the highlight of the ThinkPad line

The ThinkPad was originally manufactured by IBM before being sold to Lenovo in 2005. To this day, the line is so highly regarded that it can be considered the Porsche 911 of laptops, and has attracted a large following of fans who swear by its reliability, sturdiness, keyboard quality, and of course the TrackPoint.
