All devices have compromises. right now I'm dictating this on a new iPad.
The speaker independent voice recognition works reasonably well, although medical terms are problematic.
The advantage of the iPad is its portability. I use the iPad every day when making rounds at the hospital, connecting to the hospital information system using Citrix. I initiate a note in the patient's room, and complete it at a desktop workstation.
Having said that I do not use the iPad in exam rooms in my office, as I have desktop workstations in each room.
The point is use a device that you're most comfortable with anytime anywhere.
We coined a different definition of the abbreviation UI: ubiquitous information, using desktops in the office and at the hospital, iPad at the hospital and when I am out and about with it, notebook at home, and even a smart phone when am at remote locations.
