It contains both the King James and New International versions of the Bible. Most of the functionality comes from the search feature, which you can use to search for verses by word, phrase, or reference number. Some of the more difficult and archaic words can be defined using the Holman Bible Dictionary, which is also integrated. The electronic dictionary can also select verses for you to memorize, and can be made to produce inspirational quotes daily.
The Electronic Bible and Scripture Dictionary requires two AAA batteries to operate, and is available for about $100 off Hammacher Schlemmer.
