this is OT but whats the diff between a mech keyboard and ur average 30 dollar usb one?
Well the average 30 dollar keyboards mostly use rubber membranes... some people might prefer that, but I am not one of those people. That being said, I do like some of the laptop style keyboards that use rubber membranes and a scissor mechanism. Mechanical keyboards are in a whole other league (in my opinion) and they offer much more tactile feedback when typing, they seem less fatiguing to my fingers, and I happen to be one of the people that prefer that "clack-clack" sound they make!
Now there's different types of mechanical key switches too, and some prefer one over the other... me... I have always liked the Cherry MX Blue key switches myself, which is exactly what are in the Black Widows. These have a very short actuation distance of 2mm and they still offer plenty of feedback even at that short travel... this allows my to type and process keystrokes much faster than I can on normal keyboards. The mechanical key switches are also more durable and last longer than traditional rubber membranes... and did I mention that they just kick ass!
That was a bit long-winded I guess... but hopefully it gives you an idea of the differences, well in my opinions at least.
