real man use wired

Wireless keyboard not only introduces higher latency but also security risk for keyloggers.

Someone can steal your keystrokes and steal all your password if not properly implemented.

Wireless later USB receiver malfunction, lost, stolen or got eaten, cry mama cry papa!

wireless there will be delays, albeit u might not notice it, personally play assassins creed,
bioshock, doom type, doesnt really bothers me, but suspect delay in some occasions.
casual gamer anyway.

Good, because 5 out of 10 customers bought wireless KBs from me and asked me where to get a replacement USB receiver after some time.
