The Hobbit - J.R.R. Tolkien
I give this top ratings. It is a very fine and complete unabridged audiobook. So I'd like to address some of the issues I saw from others.
Yes it is only two main tracks. But it will let you select individual chapters within the 2 tracks. So instead of using Skip, you'll have to select the chapter manually. Just like any other album.
It will remember your position. By default it does not. All you have to do is open it in iTunes and edit the options. There is a checkbox to make it "Remember position". You must set the option to 'Yes' IN ADDITION to checking the check box.
So problems solved in my book. I will by the other three by Rob Ingles. :)
