I generally like audiobooks, especially the Amazon’s ebook+audiobook combo. It allows me to continue enjoying the book in places where it would not be possible otherwise, like when I have to do something boring.
The only aspect I don’t like about them is the inability to adjust the tempo. With a regular book, I always accelerate in less interesting parts and slow down where it matters most, often re-reading the same passage a few times, and this freedom to change the tempo is important. So important, that sometimes I have to stop the audio version of the book and wait till I can read the text myself to fully enjoy it.
