These keyboards come and go but, in the end, the QUERTY has stood the test of time over many, many decades, from typewriters to computer keyboards...:-)
It was originally conceived to prevent the original typewriter type bars from sticking together as they moved through approximately 90 degrees up and back again; the principle was exactly the same in that it kept the most used keys apart.
Christopher Latham Sholes, the inventer of the typewriter, devised the method a little while after the first typewriter hit the market from Remington in 1873.
He rearranged the keyboard from an alphabetic arrangement to one in which the most common pairs of letters were spaced reasonably far apart on the keyboard, thus preventing a type bar catching/locking up with another one.
As I said, it's stood the test of time.
