Hello,
I am very new to e-book devices and unfortunately don't know much about them.

I'm looking for a device which I could use to read books and listen to audiobooks (I often do these two at a time on my laptop). I commute a lot and think that a mobile, light and pocketable reader would be an excellent way to use the time I spend on various means of transport.
I'd really like one device with big memory (audiobooks usually take up lots of space, for instance the folder for e-books and audiobooks I have on my computer takes up almost 20GB), handling various text and audio formats, and possibly with good battery life.
What would you suggest please?
