The G11 doesn't have the LCD display, that's the G15. I have a G11 and I think it's great. I needed because it's much more durable than my previous keyboard, and a decent price for a gaming board too. Looks nice, the blue fits the rest of my PC, and the function buttons are useful.
Some people have complained about the quality not being 100% but I really think that must have been a bad batch as mine is newer and just great. It's pretty big, but that's no problem, keys are fairly widely spaced. The USB ports are quite useless though, as they're USB 1.1, and don't have enough power even for my pendrive.
Certainly worth considering if you don't need a little screen in front of another screen and want a decent quality gaming board with nice solid key feel, as well as a few features.
