I think Webster's 1828 Dictionary is a great dictionary used by many in preparation for their sermons as far as looking up definitions from dictionaries, since it is one of its kind, so full and complete and with scriptural principles used as examples at times. There were only a couple of things that made me hesitate on making a switch to Logos for a little while, and one of those was that 1828 Webster's isn't in Logos, and the other was certain features a simple program such as Sword Searcher has, tabs for different books and commentaries, and Logos implemented those kind of features in it's latest release, which is great!
