Kindle Paperwhite vs Nexus 7


I am truly confused. I want to buy a "tablet/ ebook-reader" for Primarily reading books.

I like the Kindle Paperwhite a lot as its great for reading books. And that will be my primary purpose of a tablet.

But it kills me to know that I can not do anything else with it, like occasional games or music even. And NO. I don't want to carry TWO devices.

So what I am really asking is how good/bad is Nexus 7 for reading books daily for about an hour or two. And am I better off buying a Kindle, just for pure reading pleasure or will Nexus 7 also get the job done and give a bunch of other features.
