Disadvantages of the Qwerty Keyboard
It's Ineffective
The QWERTY keyboard was designed so that the most frequently used keys would be placed away from one another. While that proved useful for dealing with typewriters, many people argue that it's ineffective. In "The Dvorak Keyboard," Dr. August Dvorak claimed that typing common letter combinations requires making awkward and uncomfortable finger movements. In addition, most typing on a QWERTY keyboard is completed with the left hand, when in fact most people are right-handed.
It's Ineffecient
Dr. August Dvorak also argued that the QWERTY keyboard layout is inefficient. He claimed that 30 percent of QWERTY keyboard typing is performed on the lower rows, which are the hardest to reach. Furthermore, another 52 percent of typing is performed on the topmost row, which forces typists to move their fingers further away from the home row.
It Has a Steep Learning Curve
Due to its arbitrary design, a QWERTY keyboard can be difficult to master. This especially holds true for young children and the learning disabled. One alternative to the QWERTY keyboard, known as the alphabetical, or ABC, layout, has all the keys laid out according to the alphabet. The top-left features an A, while the bottom-right holds a Z.
It's Slow
The QWERTY keyboard is especially inefficient, ineffective and slow on mobile devices like smart phones. Mobile devices are small, so users typically only use one or two fingers to type. And since frequently-used letters on a QWERTY layout aren't grouped together, it can be very time-consuming to just write a simple, two-sentence paragraph.
