This again tends to be a 'generation' choice.
I have grown up with albums on vinyl, the news in a paper, and books in book-form, and apart from the switch to CD's, have remained true to my formats.
I appreciate that for young people growing up, kindles and MP3's are as current to them, as the former formats were to us - so they feel comfortable with them.
I still prefer a real book, but then again, I prefer to sit and listen to my music, not simply have it on as background while i do something else.
As my fifteen-year-old grand-daughter loftily informed me - I am "so last century!"
