Here's an illustration of why I like Logos...
Been telling my pastor friend he needs to get Logos. He said, "I had it years ago, but not anymore." Back in seminary, he bought Logos Scholars on sale, and loaded it on an old computer that had been given to him for use in seminary. After he finished his language studies, the old computer died, the discs went in the bottom of a filing cabinet, and Logos was forgotten.
Six years later...
My friend found the old Logos discs. He tried to load them to an XP computer, but with no success. By chance, he called customer service. They said, "Yeah, we still have your name in our records. Here's how you can download your files. My friend is now rediscovering his Logos library on his Apple I-Pad.
Logos selleth and it's still yours!
