I care about the nook, it's a great eReader, and I use it daily. I suppose you're referring to the iPad, which isn't an eReader.

It's not an e-reader but you sure can read on it. And when you're done reading you can watch something. Or listen to music. Or play a game.

If you only want to read then the Kindle and Nook are great devices. As always it's entirely subjective and depends on what you personally want from the device (and how much you want to spend).
