The legal industry has been slowly moving from its analog paper existence towards digital document management for a couple of decades now, but as with any paper-intensive industry, the evolution is moving at a snail's pace. Fortunately, there are a hefty number of document management tools out there to facilitate a business's move to digital file-sharing.

Sony's Digital Paper — a device that allows users to annotate, share, and save documents in conjunction with a cloud service on one device — is one such technology, and the company recently improved upon its firmware through a collaboration with Citrix.

Sony's Digital Paper is a tablet that is thin, lightweight, and optimized for reading and annotating full page documents. With a touchscreen and stylus, users can write fluidly and directly on the panel, while easily highlighting and erase text. Sony's partnership with Citrix's ShareFile technology is a natural one as Digital Paper is a device for creating documents, and ShareFile enables secure sharing and syncing of those documents.
