I have been using a (used) Motion Computing LE1700 tablet and a Lenovo x200 tablet. Got both off Ebay pretty inexpensively.
Both work pretty well. I can take handwritten notes in OneNote, publish to PDF and import them to AC.
That way my handwritten scribbles and any diagrams, etc. that I make are archived in electronic form.
I also use a combination of Dragon voice recognition, AC templates, and some handwriting recognition. I'm getting better and more efficient at all of them, though as noted above, there are some howlers of mis-recognition.
I put orders and Rx's in while seeing the patient, but I tend to review and complete my notes after office hours -- I hate trying to document at the same time I am with the patient -- I find that rude and distracting. Having the PDF's of the notes I take in the exam room is very handy, and is nearly as "natural" as taking notes on paper.
The one problem with the tablets is the miserable battery life (and the heat they generate-- they get pretty warm sitting on my lap.)
