The release dates of keyboards were never really something I took into account. Its only with my current one that I have looked to see when it was released to try to guess when next version will come out.
it coming out in 2014 makes me wonder what i used before it. Might have been the Razer keyboard.
I think I used the G910 for about 5 years or so, it was still a good keyboard when I stopped using it. Its only fault was I had accidentally broken its home key at one stage, but that was on me... it was still attached, it just didn't work so well. I never really use the key.
That and Logitech swapped the software they used to control their hardware a few years after I bought keyboard, from Logitech Gaming Software (LGS) to Logitech Hub, and for a while after its release I couldn't change any of the rgb colours.
Reminds me, LGS didn't use the windows scaling for the desktop but instead used native. Windows by default scaled my 4k monitor to 150% to allow people to read it easily. But since LGS used 4k, I needed a microscope to see it on screen, At least the hub software used windows desktop scaling.
