Mine says he wants nothing as he "has too much stuff" and "will only end up breaking or losing it" if I buy him something nice (we have had words about this in the past!).
But obviously I can't get him nothing for Christmas - in fact I've just had a promotion and would like to treat him. But he is right, he does tend to lose and break things and I don't want a gift to lead to upset. Perhaps I need to look for for an experience or a consumable than a thing to keep. 
Tell me your good ideas please and let me steal your inspiration!
