As long as there’s a viable method for archiving legal documents, it’s a great idea. However, throughout the country, varying cities, counties and states have different requirements for legal documentation. Many require an original hard copy of said documents. This may not necessarily be limited to legal documents in some cases. My point being, in many such cases, you simply cannot go paperless. Still, an electronic archive is tremendously advantageous, provided you can pull the hard archive as needed.
It appears this is just for preparing what they read, from sources already in digital format. It shouldn’t change anything unless they start using the iPads to create official government content.
I had arguments with high-level managers, as they wanted to incriminate employees for things stated in emails. They would flash print-outs of emails to me as grounds for firing people. As an IT systems engineer overseeing our email systems I showed them how easy it is to spoof origination and target addresses with email. I could effectively make anyone look like a criminal, even these managers, by inserting faked emails into the system. And not just me, anyone with sufficient IT knowledge can fake electronic documents. That shut up the managers.
