haha fair play probably asked for that! Guess i'll do a little digging i've heard they are good.
Few reasons (I'm sure there are more!):
- Gaming - they offer more desk space for FPS players who use low DPI's and thrash their mouse about in wide arcs.
- Portability - LAN's, laptop users, elite haxors plugging into a mainframe, etc.
- Aesthetics - They look great!
