Gadget-addiction?

Why is it that us men are completely addicted to gadgets? It might be different kind of gadgets (cars, tools, computers, kichenequipment etc.) but we always want the best and the newest type of gadget in the field that interest us. Take this projector for instance, when I saw that I thought: "I want one of those! they look sooo nice and stylish!". As allways though, I probably can't afford it, and I really have no use for it since we haven't got the space for it to be used to it's full potentiel....but still...they do look nice :)
