Input: They come in 2 colors, black with white lettering, and white with black lettering. I have 2 pc's in one room hooked up (one in a white case, the other in a black case) and they both work fine. I have a PC in another room with this keyboard, and use that fine.<br /><br />They take a little bit to charge up, but completely charge and drain the battery, do that several times and your battery will last a long time between charges. It takes several charge discharge cycles when they are new to get the longer running times.<br /><br />That has been my experience.<br /><br />the usb receiver dongle is black, regardless if it is a white or black colored unit.<br /><br />It is great as a simple remote control, works with every version of linux and xp, win8 machines. I have not tried it on win7 machines, but it should work.<br /><br />works great with the wonderful xbmc program, either windows or linux versions. Great buy for less than 20 dollars. for 45 dollars I got 3 keyboards and when not in use I stack them on my desk taking very little space.
