Great option for travel. I take my m10 along on trips and try to seek out local talent, but if I had an iPhone this could be an alternative (the m10 isn't big, but it's one more thing to carry/lose/get stolen). I see this as a gateway drug potentially drawing more people into the hobby. Start with the iM2>iPhone, realize for a few hundred more you can move up to a Church Audio>m10 type rig, and then for a few THOUSAND more... you know how the story ends.
