I have a Kindle (not fire, just a reader, but I love it), and also an iPad. However, while sewing I like to listen to audiobooks, which I borrow from the library. In fact, I've been known to download the audiobook CDs into a playlist on my iPod (can you tell I like electronic gadgets?) so that I don't even have to change the disc every hour or so.
In your case, I'd choose the tv.
