Sims/Logitech Collaboration (Winner Announced)

I had a Logitech G15 (the old one with the flip-up LCD screen), followed by a G510 and a G512 Carbon. I'm currently using a simple K120, just a cheap, functional Logitech keyboard. I'd had mixed (poor) experiences with the G510 and G512, enough to make me not want to bother with gaming keyboards any more. I still like Logitech stuff.
The idea of having mood colours adjust the keyboard RGB is pretty good though, and I hope it is well-received.
