In 1979, Dan Bricklin wrote the most innovative piece of software in history. Before VisiCalc, there was nothing that remotely resembled an "electronic spreadsheet." After it, the world of business was different in deep and fundamental ways.
His attention has shifted to the tablet marketplace, where he runs Software Garden, purveyor of Note Taker HD -- a top-of-the-line iPad app for taking and organizing notes via either keyboard or electronic ink. He was kind enough to share his thoughts on tablets, inking, character recognition, and other, more important topics.
