Yesterday I read a couple of excellent blog posts in which the authors made good use of Accordance.
Rubén Gómez of Bible Software Review interacted with a text-critical question raised at Evangelical Textual Criticism. Rubén used the various tagged uncial manuscripts in Accordance, along with the CNTTS textual apparatus, to examine variations in Luke's genealogy.
Rick Mansfield of This Lamp used Accordance (and print resources) to examine the proper interpretation of Matthew 5:28. In addition to comparing multiple translations and consulting BDAG, Rick found A. T. Robertson's monumental reference grammar of Greek to be especially helpful.
Be sure to check out both posts.
