From here.Caps Lock had its uses back in the olden days. [...]
By the 21st century, Caps Lock had become an outdated scourge. Modern-day personal computing—surfing the Web, writing school papers, chatting online—doesn't require nearly as much capitalization. As of 2010, the most-common Caps Lock users are enraged Internet commenters and the computer-illiterate elderly. The key's location makes it a frequent target for an aCCIDENTAL STRIKE when your pinky reaches for the "a." Worst of all, Caps Lock occupies prime real estate that could be deeded to a more useful key, like Control or even a second Enter button. In 2006, Belgian computer programmer Pieter Hintjen launched the "Caps Off" campaign to persuade hardware manufacturers to abandon the key. Their slogan: "STOP SHOUTING!" Many online publications ban comments that are typed in all caps. Some people pry the offending key right off their keyboards in protest.
So why has Caps Lock stuck around so long? The simplest explanation is technological inertia.
