Why the OnBoard Travel Keyboard is easier to use than a laptop
keyboard
Most people find that their typing productivity (speed and accuracy) is
lower on a laptop keyboard than on a desktop keyboard. They have to
type more slowly on a laptop keyboard in order to maintain the same
accuracy, otherwise they have to spend a lot of time correcting
mistakes. Although there is a difference in feel between the
“membrane” switch mechanism typically used inside desktop keyboard
keys and the “scissor” switch mechanism often used in laptop computer
keyboards, this difference does not fully or even substantially account
for the difference in typing productivity. Nor does the spacing of the
keys. The general impression is that laptop keyboards are cramped, and
although it is true that laptop keyboards do not have separate numeric
keypads, careful measurement of many laptop keyboards (not including
miniature types) shows that the spacing between the centers of adjacent
keys (called “pitch”) is the same as or very close to the pitch on a
desktop keyboard! And the width of the keycaps is about the same too.
So why are laptop keyboards harder to use than desktop keyboards?
The reason a desktop keyboard is easier to use is because of the
height and shape of the keycaps and the amount of distance they
travel.
