Thought I would mention that for Kindle (and probably other e-book users) that the free Mobipocket Creator (Publisher Edition) is great for converting various formats into Mobi which the Kindle seems to handle better than other formats, especially PDF.
The Mobipocket Creator is available here.
Last "electronic book" I tried is the Franklin Bookman, so I wouldn't have to lug (and perhaps damage) a Bible while I was traveling a lot. My wife bought it for me around 15 years ago.
I rarely even think about it, let alone use it; instead I pick up a 5 pound large print edition....
Forget it; sorry I asked the previous!
$360, plus just as much money for each book to read on it, as I pay for paperbacks or used HBs anyway.
And no batteries to go dead; other people’s servers to go down; too many places around here that I can’t get reception—tied to wires; I’ll stick to print.
