While the LCD is capable of displaying in-game info, Logitech has put the responsibility on the game developers to implement the LCD software. Therefore, at the time of testing, only one game, Brothers in Arms: Earned in Blood, supports the display. This lack of support renders the LCD virtually useless.
True, Logitech provides a full, free SDK for the LCD, allowing anyone who knows how to code in C++ to develop homespun applications. Still, I would have liked Logitech themselves to have been a little more proactive in creating code for their own product. It really isn’t the game developer’s, or the end user’s responsibility to develop support apps for someone else’s $80 keyboard. Hopefully we will see better implementation of this feature in the near future. 
Conclusion
For around 70 bones, the G15 is definitely not cheap, especially for a corded keyboard. However, there are several unique features that differentiate it from the competition. The “G” keys can be very useful to MMORPGers, and are super easy to use; the game switch and integrated USP ports are neat little bonuses; and the backlit keys are undeniably cool, although not unique to Logitech.
Unfortunately some of the G15s potential charm and utility is lost in the lack of support for one of the key features, the LCD. Still, I was very pleased with the overall performance of the keyboard and its support software. I had a few minor issues with the aforementioned software, but my problems were immediately addressed by a technician, and a patch that clears up all glitches will be available VERY soon.
