The major difference in the keyboard is the type of mechanism used. At first, the membrane keyboards were cheaper to produce, with little tactile feedback and more commercial. Later they evolved, this type of mechanism is also present on many models by gamers.

The membrane looks like this:

In the picture, the new Raptor Corsair K50, that uses a membrane system.

In addition to the membrane, there is the well-known mechanism Cherry MX typical of mechanical keyboards. There are different types of Cherry MX: black, red, blue, brown and clear.

Black and red are typical for the hardcore gamers.
Blue is typical for the writers.
Brown and clear are a hybrid suitable for gamers and writers.

Following, a pic of a Cherry MX Red (from Corsair K65).

GHOST problem

The phenomenon of ghosting is a problem that affects most of the keyboards economic / non-gaming and it appears when you try to press a key combination. Usually, these types of keyboards are able to detect only the signal of two buttons. This problem exist a cause of an electrical and design restriction. Not all combinations are, however, ambiguous or difficult to recreate for the keyboard.

Many manufacturers have invented a method called "no-ghosting" that limits and sometimes resolves the problem. Analyze together the various types:

-2KRO: allows you to press 2 buttons simultaneously

-3KRO: allows you to press 3 buttons simultaneously

-6KRO: quite rare, however, allows you to press 6 keys simultaneously addition to the SHIFT, CTRL, ALT and ALT GR.

-NKRO -(N-KEY Roll Over): each key is analyzed in a completely independent way, so any pressure is correctly detected. NKRO has not a limitation of simultaneous pressures.


Keypuller
The keypuller is a tool very useful for remove the keycaps.

Polling rate
The Polling rate is the frequency of refresh between your keyboard and your computer. It is measured in Hertz. Usually the steps are: 125 - 250 - 500 - 1000

True, maybe some manufacturers have a few things in their backpack for CES. I'm quite curious about CES 2014 anyway.
