Paper is so 20th Century — or so it can appear when looking around at all the astonishing tools and applications now used in the practice of law.

To be sure, all these applications make life easier. Paralegals no longer need to photocopy rooms full of paper, the better for lawyers to pepper them with inscrutable sticky notes and highlighter markings. An associate can slide a notebook computer into a backpack or slip a thumb drive into a pocket rather than heft wheeled carts stacked with banker boxes. And partners need no longer incur the wrath of typists wrangling sheets of carbon and bottles of white paint to make edits. One can simply cut, paste, delete and rewrite at will with electrons on a screen.
