I have a friend who bought an iphone 3g a while back. His justification for buying what others may consider an overly ostentatious product, is simply "I can and I want it".

I like his reasoning. He wants the iphone regardless of its price. He likes, no, simple adores it. He's not rich, a guy with an average monthly salary, but he does have a little leeway in his spendings. He saved up and actually bought one.

Others thought that he could've spent the money on new clothes, shoes, a better notebook etc. Right now, he's a happy owner of the Iphone 3G, not because his job demands that he has one, nor is it he is in need of such a gadget, but simple because he wants it and he knows how to fully utilize it.

I'd say that's justification. Nothing's more satisfying than earning something you've worked for, regardless of the price tag, be it cheap or expensive. Because everyone needs their daily poison once in a while.
