The portability of the new unit is really nice. But the new foot section of the new boots is really the best part for me. I guess I'd always just figured out a way to bring my NormaTec with me, since it was so important around a race. So I was just used to it. But if the idea of bringing yet another thing with you to a race was keeping you from buying the NormaTecs, then the portability is a huge positive.
EDIT: for clarity. some mistakes regarding internals.
