I'm typing on a G19 right now and have never had a ghosting issue on it. My standard keyboard is a SideWinder X6 (because the keys are more fluid and better for typing and gaming, since I do far too much of both), and I've also never had a ghosting issue there. But the X4? Sure, I tested and had a hard time finding any ghosting, especially compared to the X6 which sucks when it comes to ghosting...but is ghosting actually a problem? Is Microsoft solving anything with this keyboard except...
