You can get and root a Nook Single Touch, which will allow you to install a reader program for whatever format you want to read. You do have to root it, but there's programs that can do that for you. I've root my Nook HD+ Tablet and it was easy. I think the Nook has text reflow for PDFs - can anyone confirm that?
Even better, they're on sale today for $50 from Best Buy. I'm jumping on that since I've been thinking of getting one for months.
