I use my tablets everyday. My main ebook reader is my Galaxy Note "phablet."
I use my larger tablet for:
- reading the news via rsss
- watching music videos while I do dishes
- as a music player - partnered with my Bose Soundlink Mini speaker via bluetooth
- reading music while I play my mountain dulcimer
- playing games
- checking weather and more
I have a laptop as well that I use for presentations and work while travelling, but the tablet is more portable to move around the house for all the other things I use it for.
