So I decided between the S3 IS or the S5 IS. I need to know if the S5 is worth buying over the S3? I'm going to New York City Saturday and if I choose the S3 I can buy it for $250 with memory and have it before I leave. If I decide to go with the S5 for around 330-350 I won't have it for NYC. With that in mind is the S5 worth the extra money and the wait?
