Input:
This keyboard is superb for typing with.  The wrist support does what it is supposed to and keeps your wrists very comfortable.  The keys are solid and do not get jammed easily like my former eMachines keyboard.  It is also not excessively loud like my Dell Quietkey Keyboard.  It is superfluous because it goes beyond being a great keyboard by offering some great nifty button things.  Although some of the buttons are very useless for me, like the back, forward, stop, refresh, search, and web/home because I use keyboard hotkeys, but the others like the mute, volume, calculator and my compputer (which I programmed for my own things) are extremely helpful.  Even though some are useless, they are just extras that don't hinder anything.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: A: very positive
