So, I'm on a trip and can't check out Google Health myself this week (with the Internet as bad as it is in this hotel I hope I can publish this post!)
So, instead I give you the next best thing: What other people are saying about it:
Hospital Impact not only does its own review, but links to six other articles on the new site.
The Health Care Blog also weighs in.
Tom Foremski writes it up for zdnet, but it's based on being at their launch, not an actual review.
If you mostly care what someone who really has spent time on the site thinks, go no further than the first link above and Tony's review.
