Nokia 6600 Fold carries the name of a very famous predecessor, one which was hugely successful for Nokia and was selling well for almost 3 years after its launch. 6600 Fold is a different species altogether, more endearing to fairer sex i.e. less complex, more good looking, and quite expensive. It reminds me of the Sony Ericsson Z610i, which was very popular with the women in Pink and my girlfriend just refuses to let go of it, even if its dying on her from time to time. This time I will probably be able to wean her off it with the 6600. Below is the review of the Nokia 6600 fold by GSM Arena, which is entirely unnecessary for the target audience (Women), but probably usefull for the opposite sex trying to find a perfect gift for their ladies.
