Currently, the Kindle editions of the New Oxford Annotated Bible with Apocrypha (5th edition) and the Catholic Study Bible (3rd edition) are available for $9.80 each. The list price for the Kindle editions is near $28, and the current price is the lowest in the past 30 days. I have physical editions of both and use them regularly for Bible study. In light of the low price, I just purchased both Kindle editions for ease of reference while traveling. I occasionally bring one or the other of these study bibles with me when I travel, but they are bulky and take up valuable space (and weight) in luggage.
From brief usage of the Kindle editions so far, I would say navigation is acceptable, but not impressive. The hyperlinked notes in the Catholic Study Bible are almost always paired with a cross-reference hyperlink. This led me to multiple failed attempts to access a footnote, where each tap of my finger sent me to the cross-reference instead. Navigation works better in the New Oxford Annotated Bible, where tapping on a verse number leads me to the general section of the footnotes related to that verse. Both editions have links to the beginning of each biblical book in the table of contents, but not verse-by-verse links to look up an exact verse.
