Gorgeous display. Electronic search. Mobile.
No way to print and document why you made the decision you made. Even in a web browser on a computer, try to print anything and they say you exceeded your limit for the day, even when nothing prints. At the national specialty meeting in October, the manager confirmed screen shots are your only documentation option.
I prefer a book such as the many books I purchased in inkling, but at work find myself almost exclusively using a different service which pre-digests the information. I am still responsible for the final decision I made, but with inkling cannot document why. The earlier interface was not as pretty, but much more useful.
