Don't ask me why they left out the first 'n' there.

Because typing the sequence u-n-m at speed is really quite difficult.

It's also the reason that it's perl and not pearl.

Same as it's hard to type t-h-e correctly all teh time, nad typing
a-n-d is a bit of a pain too. Anyone would think that the qwerty
keyboard layout was designed to slow down your typing speed...

I don't remember where, but I read somewhere that the qwerty layout was not designed for raw speed (as some people think) but was designed for speed on _mechanical_ typewriters. i.e. part of it's design is to maximize the possibility that you'll alternate left-hand/right-hand, thus minimizing the possibility that the hammers that fly up and strike the paper won't jam. (probably most of you have never used a truely _manual_ typewriter, and thus don't understand the mechanics ... manual typewriters use hammers, much like a piano, that have the embossed letters on them, and you have to hit the key hard enough to cause the hammer to fly up and strike through the ink ribbon and put the image of the letter on the paper. You also had the possibility that if you tried to type too fast, the next hammer would hit the first hammer as it was on its way down, thus jamming the typewriter and requiring you to stick your hand in the mechanism and unjam it, which meant you probably got ink on your hands ... _unlike_ a piano, all the hammers with the letters on them were angled to strike the ribbon/paper at exactly the same location, thus the possibility of collission was very high.)

Anyway ... the fact that the qwerty layout was adopted for electric
typerwriters, and later keyboards that don't have the same restrictions as
manual typewriters is an unfortunate consequence of "let's use something
that everyone already knows."  It would have been better if the folks who
developed the electric typewriter had used the Dvorak layout, but it's
unlikely at this point that the world will switch.

If you've never seen a mechanical typewriter, it's an interesting history
lesson.  It will explain a lot about why the keyboards we use today function
they way they do.  Just wait until you learn how the SHIFT key used to
function!  ... I wonder if I still have that old cheapo typerwriter in
the attic somewhere ...

I remember those!! I used to love hammering as many keys at the same time as I could. My parents would spend ages "unjamming" it afterwards. :-D
