Have you guys tried using more than 3 keys at once on a wireless multimedia keyboard?
I have a MS Arc keyboard, and it will not read even a 3rd key pressed simultaneously. example: I cant run with (SHIFT +W + D) I either move fast straight or side ways but not diagonal, if I move diagonal I dont run ...so it only registers 2, where as my MS wired one is better it has a higher limit I believe...I dont knw telling from experience.
Then another example is from Dirt 3, or the older CMR series, I played them a lot on keyboard as well as wheels, try a normal wireless keyboard if I remember it was a logitech one, first I get a warning about "Sticky Keys" Then I have issues with key strokes not registering when I do a quick tap to correct the Cars direction....
And yes most of the so called gaming keyboards have macros and backlights etc yeah you can call em bling, but the backlight helps to just get a quick look at the keys in the dark, most of us who type a lot know where which key is even in the dark, but it helps. Macros, even in FPS many gamers use....Reload and Quick Switch Guns or anything....I personally dont use any.
My use of a gaming keyboard is one that would last me a while after all the key smashing I do. I am not able to keep any keyboard more than max 6 months or so and its not a joke any more. Do you guys realize how many more times ASDW is pressed while playing a FPS compared to when one is doing regular typing? Its gonna be way way more, How quickly are you gonna reach a million key strokes on those 4 keys alone whereas compared to the rest of the board? I hope you guys can tell what I am trying to point out here.
I am not saying go and get a gaming keyboard, but just to understand what they are for and they are not really there for you to higher you FPS score, or RPG but maybe give you a bit more of comfort while gaming, maybe give you a handy macro so you can cast all those spells at once (Razer, Logitech even MS has some now...), or maybe a glowing key which you can see in the dark, or maybe what your core temps reading is at, or maybe nothing but a bullet proof board that one can smash fellow gamers with

(Steelseries has no bling!!!). They are all there just make a conscious decision.....
