Well, if the sound is actually more closely related to the 1st gen shuffle, then I will be very happy with my iPod. I already own the first gen shuffle which when combined with my previously owned super.fi pros first brought me into headfi. It will probably always be my ultra portable, second would be the iMod, third would be the iMod with Corda Move, and my transportable is the iMod with vCap dock and Move.
I REALLY want to know if the 160 GB hard drive will not only double my storage, but give me better battery life IF it works. I'm going to be switching the two through Vinnie by Christmas if so and if possible.
