Regardless of the pros and cons of using computer media or paper versions, the important aspect is that you read the stuff.
If you give somone a computer version of a manual and that person is uncomfortable with it then the discomfort will be a distraction.
IHL has a valid point in that the reader of a paper document is liable to gain knowledge beyond what he is looking for. On the other hand; when using computer media you seldom use the table of contents. If you are looking for something you can usually use a search engine, which will find everything in the manual concerning the topic you are looking for. That can have the same result to some extent.
I have seen many manuals on computer media that have been difficult to work with or unreliable/unstable. This is often due to the publisher having too high technological ambitions and making it too complicated. They often lose sight of the fact that it is to be used by people and that the important aspect is to provide information rather than fancy software.
Keep it simple and use tried and simple software and it will usually be reliable and simple to use.
