[Dec 2018 Update]: After who knows how many years (bought it round 2010 maybe?) I still use this keyboard for many hours a day, and it stays almost as good as when I bought it for $ 600 on REA. Nothing is broken or damaged. Unfortunately, keyboard with LCD screens has disappeared completely from the market, which means I'll probably use this until it dies. The software is still supported without any problems (ie, no legacy programs made by some manufacturers with old products) and while there are no more applets developed, they already work very well. I mostly use LCDSirReal with CoreTemp, GPU-Z and Fraps integration and sometimes I also use MSI Afterburner (which still supports it). Sometimes it is surprising how many programs still support the small LCD. Then I can not live without G tangents. I use them for anything from command to game to audio settings (bass, rotation, equalizer presets, channel copy for surround etc) to fast-written responses in games to turning on / off secondary screen, running specific scripts, and more. However, the built-in light card is still worthless and should never be used (if it even works).
Terrific good keyboard loves the design and the LCD screen ^^
You can choose any color as wallpaper for the screen and keys.
The G buttons are wonderful and you can let them do anything else.
It also has support for all G15 applications.
There is only a slight problem when connecting a microphone such as a keyboard. And it takes seconds for keyboard to work after you exit power save mode, hope this problem will be solved in software updates. But there is no problem complaining about =)
