According to some research done in Australia, the colour of your mobile phone says a lot about you. The research found that Aussies have stronger colour preferences. If you have a stone grey coloured phone then you are sleek, cool and modern. If you like bright colours then you live in Queensland. If this survey is real then I think its rather bizarre my self 
I just went for the silver N73 because thats all that they had in stock.
