To understand Lenovo's concern, turn the clock back to the 1800s.
Back then, fast typing would jam typewriters, so a keyboard layout that slowed down flying fingers was devised. The commonly used "A" key, for example, was banished to the spot under the relatively uncoordinated left pinky.
Typewriter technology evolved. Mainframe computing led to function keys and others of uncertain use today. The PC era dawned. Yet many laws of keyboard layout remain sacred, like the 19-millimeter distance between the centers of the letter keys.
Tom Hardy, who designed the original IBM PC of 1981, said companies have tried many times to change the sizes of keys. That first PC had a smaller "Shift" key than IBM's popular Selectric typewriter did, and it was placed in a different spot, in part because the industry didn't think computers would replace typewriters for high-volume typing tasks.
IBM reversed course with the next version to quiet the outcry from skilled touch-typists.
"Customers have responded with a resounding, 'Don't fool with the key unless you can you can improve it,'" said Hardy, now a design strategist based in Atlanta.
