I'm at a friend's house right now using a Razer Blackwidow keyboard and man, does the fast clicking ever sound like famous musicians reborn from the dead working with YoYoMa creating music for the Gods.

My speed on the keyboard right now is about 70 WPM, but the sound my hands are making obviously outweigh the 120 WPM I type with on my budget ergonomic keyboard.

I do think that the ergonomic keyboards are better for one's health in the long run, though.
