Drethon writes "CNN has an article (are we up to the millionth article on this topic?) asking if the paperless office has arrived. This got me wondering, what are the main things holding back the paperless office? Just off the top of my head, the main thing keeping me printing out documents is the ability to spread a dozen pages of a document under review out on my table and marking it up by hand. PDF and Word markups are not too bad but they still lack the ability to spread many pages out to look over at the same time and could be improved to make markup a bit less restrictive. I do find myself printing out less with the use of dual monitors to have source documents and work under progress up at the same time, perhaps something like Microsoft's tabletop computer used as a desk will let me have at least a paperless desk. I know there are other reasons why offices are not becoming paperless. What are your reasons?"
