Jay,
I brought mine along and several people took it (and LogMeIn Ignition) for a test drive. It is very useful for looking at info on/in AC, and with the advent of the AC iPhone/iPad release, it will be an even better app for checking things.
The consensus of the folks who tried it didn't think it would work well in a clinical setting as a replacement for a computer in the exam room for making chart notes. The perspective might be somewhat different if it was docked with a keyboard, but still an inferior charting solution.
My recommendation was that folks who are thinking about tablets hold off until this fall/winter when several different products release that will re-define the tablet/multi-touch again.
As a reading/browsing device the iPad excels and I use it for my evening reader while my Kindle collects dust by the bedside.
It is also particularly useful for ad-hoc meetings, note-taking, and quick lookups of info.
There are several specialized medical apps that might make it useful for you, you might want to browse the App store - here is one link to med app reviews; (

As an example of some of the great niche apps for the iPad, here is an app that my lovely bride uses regularly (
