Only because it there, by the bed, and lighter than the iPad so it's easier to hold up. And I specified Kindle, because I obviously can't use it to read something from iBooks. Anywhere but bed I tend to use the iPad, even when reading something that I could use the Nexus for. The iPad sits by the computer. So I'd have to get up and go get it, and then it wouldn't be fully charged and ready when I wake up the next morning.
