Just picked up my first iPad this weekend, and was surprised at the screen clarity and the typing interface - more effective than I thought it would be.
Because one of the organizations that I work with is developing iPad/Android tablet applications, we have a pretty good bead on the pipeline, and I would suggest you wait a few months to see what is coming if you are not in a rush.
The next wave of tablets are going to re-define the marketplace for hand-held computing.
We'll also be trying out LogMeIn on the iPad, and see how viable it is in a clinical environment.
Downloaded the Kindle app for iPad, and it quickly downloaded my purchased books onto the iPad. The iPad has replaced my Kindle for evening and night reading - sharp,variable backlighting, and doesn't disturb my lovely bride.
Battery life is good as well - the two of us have used it on and off since Saturday, and it is still @ 46%.
Surprising amount of free medical resources; will be showing it to practitioners to get their take on the usefulness of the information.
