I use the same model of Corsair for work (I am a programmer) and find it more than worth the price of admission. I have come to the realization that most office-style hardware is mostly about keeping costs down (even when you’re past pure GI hardware). Gaming hardware, on the other hand, tends to sacrifice pricepoint in favor of hardware that is precise and comfortable to use for long periods.
Ironically, it seems like more office workers really ought to consider switching to gaming hardware.
