I have used Logos since version 1. Each version adds new features that make working with the Scriptures easier, and in my opinion, more fun. The Bible should be exciting, a book that reaches out to you and draws you to it for reading, study, meditation, moral instruction, and much, much morel Our love for God should cause us to want to read and study this fabulous Word of God. Logos 6 provides me / us with the tools to accomplish this, whether this is our first time to the Bible or a daily experience for twenty, thirty, forty years. The tools allow us to find exactly what we seek, and provide other trails along the way to wonder when we have nothing else to seek. I currently own Portfolio and look forward with great delight to the day I can upgrade to Collector's Edition.
