Mechanical Keyboards what are they and do I really need to invest in one.
You see, there are many reasons why a person would buy a mechanical keyboard:

Durability
Customisability/Aesthetics
Feel

Mechanical keyboards are probably one of the best purchases you can make regarding your computer peripherals. This is because they are highly durable and very reliable. Unlike your plain old stock Dell keyboards, which use a rubber dome in combination with a membrane film in order to register a keypress, mechanical keyboards have a switch for every single key on your keyboard. The one and only job of a single switch is to tell whether or not that key was actuated.
Now you might be thinking, how is this more durable than a regular old keyboard? see the full wiki here
