The keys on the G15 still feel responsive and I've grown very used to its ergonomics. I like to use the silly little screen to monitor my performance metrics, music playlist or just look at the clock. The media buttons also are quite comprehensive and useful. I have not however used the macros pretty much ever and the RGB backlight is fading from all these years of use.
After all this time I might finally be looking for a new keyboard to see how much gaming keyboards have advanced in the last decade. Currently I'm sort of hemming and hawing between the Roccat Vulcan 100 Aimo and the Corsair K70 RGB MK.2. I'd love to hear any experiences any of you might have with these keyboards and in general hear what kind of keyboard setup all of you are using.
