A few days ago I did what most people would call an impulse buy for a very expensive wireless mechanical "gaming" keyboard. Even though the desire for this hardware has been prevalent for many years, this kind of keyboard has only recently started to become a reality. A year ago you'd have a lot of difficulty finding a keyboard with this combination of features. Razer is the latest to come out with there attempt at satisfying the needs of the market.
All about operating systems, and networking.
