SILVERBACK said:bought the one myself as the chip in the one is much better than the go BUT the battery doesnt last as long on the one as the go (i get 4 hours 20 mins solid) but the quoted time on the one is much less than the real life battery.the speaker is better on the go aswell but to be honest the one is plenty loud for me.im sure a google will turn up a lot more info than me but id say go for the one myself.
