When you’re a PC gamer, those extra buttons sometimes are what keeps you from dying nearly as often in the game.  However, there are some mice that tend to take things just a little too far.  At this point it just seems like they’re all competing to see who can fit the most buttons into one mouse.  Which seems a little silly, because frankly after a while I start to forget what buttons go with which function.  When it gets to that point, extra buttons just stop being useful.  However, if you have a fantastic memory, you might be able to keep up with all the extra buttons. Well this Razer Naga manages to cram in a total of 12 different buttons on the side.  All of which will rest on the same side as your thumb.  I suppose if you never really set a good portion of the buttons to anything it’d give you something to fiddle with when you’re bored.  If you’re interested in getting a mouse with 12 extra buttons you can find the Naga mouse for $80 .
