Indeed it is.
That is a game changer. An audiobook is turbo convenience.
For some, perhaps. Audiobooks really don't do it for me. I like to read. I have at least 2000 books on my ebook reader. I pretty much take it with me everywhere but the shower. :-)
I tend to listen to music while I read.
However, if audiobooks will expose some of these works to people, I'm all for it.
One additional consideration is file size. a book that is one megabyte as text, might well be a gig or more as an audio file of any reasonsanble quality.
You bring up some good thoughts, and it takes all kinds.
File size is a real consideration. The Federalist Papers is just under 700mb as audio.
