At E3, there was a huge booth promoting
Fatal1ty products. For those of you who don't know, Fatal1ty is some multiple-time champion of computer game competitions. He has his own line of products now, which are ridiculously hardcore.
The keyboard has really flat keys, so you don't waste precious fractions of seconds pushing keys all the way down like on conventional keyboards, apparently. Supposedly a pro's fingers will look like they just glide over it.
The mouse has an interchangeable weight system, as well as an on-the-fly toggle for three sensitivity levels. Like if you needed to move quickly, you could set the mouse to be more sensitive. When you zoom in for a sniper shot, you could make it less sensitive to get more accuracy.
It's kind of interesting, though at the same time, it sounds extremely hardcore. I guess you need the edge if you play competitively with other people, but from what one of my friends pointed out, Fatal1ty himself is becoming overrated. At the same time, though, not many gamers have even been recognized, and athletes and sports players already do get a lot of attention as it is.
