I've been looking forward learning more about the health version of the Apple PassBook, Health. So far so good. Was excited to hear about the real-time health monitoring from the Mayo Clinic, and health data integration with Epic Systems.
Assuming the next unveil will be the iWatch, and see the integration with Health.
It's still unclear to me if Health is going to replace my HealthVault PHR. HeatlhVault's been good, but the integration is complicated.
SAMI and Simband look very promising! Apple Health has the edge for me. And with the Mayo health monitoring solution and the potential EHR (Epic for now) integration, that pushes it even farther ahead.
