Despite their similarities, not all keyboards are alike. Only for the past few years have manufacturers been pairing full-size keyboards with new computers. Some computers still ship with simpler keyboards that lack numeric keypads, function keys and directional keys. The traditional rectangular keyboards are being enhanced with wrist rests and mechanisms that allow you to angle the keyboard to your liking. Other keyboards depart from the traditional rectangular design radically, splitting the board into two pieces that can be adjusted to keep the wrists even while typing.
Some keyboards are silent when keys are pressed, while others produce a clicking sound.
Keyboard keys range from feeling mushy when pressed to an extra-crisp feel with a lot of resistance. This all depends on how the keyboard was built.
