I have an iPod, but it's now so old it won't stay charged long and it's been overtaken by the iPhone and iPad. I gave my o,d Kindle to my stepdaughter and bought myself a new Kindle Paperwhite for my birthday in December. I LOVE it!!
No more dealing with book lights or buttons since its a touch screen. It's much smaller, too and fits in my purse.
I don't care for audio books myself. I prefer to read. If I listen to something it's usually a podcast.
My husband is the Luddite.
