While on the topic of HealthVault and PHRs, the discussion would not be complete without mentioning Google. Here is a link to some screen shots of Google's prototype PHR. This is more of a PHR than Microsoft's Healthvault. My patients and fellow physician colleagues would not have a problem understanding this type of application, its functionality is very obvious. Google's prototype PHR appears to be an "end-product" rather than a set of services like HealthVault.
