I tested Google Health
The library of conditions, medications, allergies and procedures it has is really impressive.
The only thing is that I found it a little bit slow, some javascript/ajax related actions, I hope it will improve in the future.
However, I will probably not use it regularly for two reasons:
- I don’t live in the USA
- I think Google has enough data about myself (search history, gmail, adsense, calendar, reader, analytics)
A lot of people will find it useful anyway, to check their symptoms before calling a doctor or so. Google Health will be a great time and money saver.
