In the past with less up to date keyboards the numbers and arrows were as one key. So therefore the Num Lock key was used so people could use one or the other. I guess makers of keyboards forgot to take it off the updated keyboards!

There are no keyboards with adjustable key striking pressure, although you can consider the depth of the keys when looking to buy a keyboard. The deeper the key is, the more pressure it is going to take to push it down. The more shallow keys would be the best ergonomic choice, using less pressure to strike each key. You can take that into consideration and find which depth would work best for you.
On older Mac keyboards the Apple key is the Command key.
NO keyboards are input devices.

The numpad is to the right of most keyboards - the 10-key arrangement of numbers. Laptop keyboards may not have a numpad.
yes there are. Many languages have special characters and have special keyboards to accommodate them, eg, Germans have a different key set. Of course Japan, China, Russia have different key set. But even within one language there are keyboards that fix the strange key layout (Querty) that we are saddled with. there are keyboards that address the comfort problem with a split in the center and special places to rest your hands. And then there are different construction techniques with different types of key switches, some that are less prone to water damage. And then there are the location of the "special keys", the arrow keys, the numeric keypad, function keys, etc. Some keyboards place a trackball or other pointing device on the keyboard somewhere. And then there are the different interface and connection methods, from RS232 to IR signals. Given all that its surprising that any 2 keyboards are the same. There are also keyboards designed with shapes and layouts specific to the one-handed typist. There are chord keyboards like the BAT, or sculpted keyboards like the Maltron which have a frequency of use layout and mechanical key switches that make them easier to press.
