Ive put in id say a few thousand hrs using the original naga i would still consider it another experiment in making the perfect mmo mouse. You see with the naga while it will eventually double click and lose its tracking from time to time the real problem with the mouse is its side buttons. Regardless of how many hrs you might spend using it if your not accurate 100% of the time the serious mmo gamer will discard it, thats just the basic truth of the product from this gamers perspective.
Now with the g600 its strenghts lay in 2 points , its side buttons are angled so memory retention is that little bit better and therfore staight out right their its a superior product to the naga. (it takes so little else, regardless of the other benifits of the naga). Now the second one is the 4 way hat switch. Having those extra quick reaction lack of fail on access left and right buttons can be alt/shift/ctrl for 4+ total buttons isnt just brilliant , its mandatory for a mouse today and the mmo design team idea that players want to use 40+ buttons in a mmo.
Now what i cant understand, is neither razor or corsair has scatched their head at all here, its odd from my perspective as they are companies designing gamer products for gamers! Im in no means a logitech fan boy, but boy at least they are a thinking mans company.
Now onto the future of the mmo mouse, what i would personally like to see is the button thats sitting at a 135 degree angle to your thumb to be raised slightly on the bottom side corner so its easier to push (those buttons facing the bottom of the mouse) as you can never roll your thumb
with certainty on the 135 degree facing button. It would be handy in the future to have buttons that you remove and rotate and ofcourse button overlays that can be swapped to go to a 4,6,8 button pad of different sizes to cater for players with bigger hands rather then the current market research of designing mice mainly for toddlers.
As for the m95 witch im currently experimenting with. How can it be superior to the logitech without a 4 way hat switch:(, even if its side buttons are
appearing to be better on the muscle memory then initially thought. corsair might be onto a winner here. future iterations might give away the game
