BuzzPCSOS This is mostly going to be for reading books at night
I use a 10.1" Android tablet for that task. I bought two of those from Walmart for very little. (Around $80 each, if I remember right..)
The Nook app is free and fantastic, and I have about 3,600 Nook books on it. But it will also display epub generics, like those from Gutenberg Press, and possibly others that I've never tried.
I'm not sure how useful it would be as a computer, though. No experience using it for that purpose.
