I would hope that at this point that would be obvious.
Even just a laptop at a table can allow you to do things like bring your entire library with you, quickly search for a specific rules item, share documents with your players, pull up images on the fly, etc. Heck, even just this last generation we saw the D&D Compendium become a searchable database of literally every official D&D rules item from 4e, along with a character and monster builder. There is not a doubt in my mind that the shift to digital at the game table and away from paper is a) inevitable, b) already widespread, c) incredibly useful (when it isn't deliberately sabotaged by DMs who aren't willing to give it a fair shot), and d) wide open for development.
