I have really short little fingers. I mean, I know that "little finger" should alert one to the fact that it won't be much, but mine are way shorter than the others, barely passing the middle joint of Finger #4.
Why is this a problem? Because my new keyboard, which is ergonomic and supposedly hand-healthy, requires a strong push to work the keys on the top row. I learned typing in a real class, where every day we set our hands on the Home Row and learned to keep them there. That means that my right-hand little finger should operate the "Back" key without much change in hand position. Sadly, it isn't up to the task, and it really slows my typing when it takes two or even three tries to erase a mistake.
Will this bring about the end of Western Civilization? No. Could I buy a more compact keyboard? Probably. I just thought it was kind of funny that as the world rages and ruins around me, something so small can be so irritating .
