It's possible to have a paperless cockpit on an A320, but is it desirable? It's very easy to have technology for technologys sake but as a very computer-literate person I much prefer to have a paper manual I can get my hands on in a hurry, and I'd rather have 6 manuals spread across the glareshield than be juggling six windows on my laptop trying to find the information I need. Everybody knows how a book works, not everybody knows how a laptop works and in high pressure situations I don't want to extract my laptop (company property, billable for damage), boot it up, access the appropriate page then find I get the Windows 'blue screen of death'. Give me paper any day.
