A:AnswerResponse time hasn't been much of an issue for me, but make sure the receiver isn't hidden away. It works great in a USB 3.0 hub under my monitor, but occasionally misses characters when it is behind my tower on my desk.
A:AnswerYou don't need windows. It charges using regular indoor lighting. There's a button on the keyboard you can press to tell you how good the light is to charge the keyboard. I'm using as standard indoor light and haven't had any lighting issues.
