Bad Tech, again

I have a wireless keyboard.
It just stopped working.
The wireless mouse (on same box) is fine.
I have replaced the batteries: still not working.
I am typing this on spare keyboard, plugged into keyboard socket, so it's not that.

They're getting cheap (Superdrug £18 in vile colours) so I don't mind replacing it, but does anyone have an explanation? Apart from sheer cussedness of technology?

Also, a quick question. Answer carefully, as the answer may affect you.

"Any Christmas card is improved by the random addition of black fur." True or false?
