I don't know what you consider "academic", but while I can see a lot of study bibles including some discussion, I doubt that most study Bibles take a more secular or less conservative look, as I would bet that most are written for conservatives and by conservative organizations.
If you don't need a physical Bible, then I would tell you to get e-sword. http://www.e-sword.net/downloads.html It has a number of different translations of the Bible to read from, such as:
The English Standard Version
The King James Version
The Jewish Publication Society Old Testament
Greek Bibles (with word translations)
Hebrew Bibles (with word translations)
Translations in other languages.
The Geneva Bible
etc...
You'll also find some versions with the Apocrypha, which you will have difficulty finding in most Bibles(which are Protestant in outlook), but which was important for the early Church Fathers.
Additionally, you can download commentaries, such as John Wesley's notes, and Geneva translation notes. As well as dictionaries, encyclopedias, and books related to the Bible or it's interpretation.
Further, the program comes with the ability to search for words.
And, a lot of the downloads are free. You'll have to pay for some, but none that you strictly need.
Maybe this will help a little bit.
