Okay. I'll admit it. I'm an Amazon/Kindle snob. I've been shopping at Amazon.com for years, so, naturally, when e-readers got popular, I bought a Kindle. (And, yes. I did compare the various readers before making my choice.) I like the features of my Kindle Keyboard, and I like the user-friendly web design, the reader reviews, and the service at the big A.
When my mom (the little traitor) bought a Nook and asked me for help, I found it difficult to use, and I found Barnes & Noble's website difficult to navigate. Of course, if she had wireless in her house, it might help. *pointed stare at mom*
Now before you assemble a torch-carrying mob and head my direction, let me say: I do like B&N for their in-person service, namely helping me order books in the past, and I love their stores. I also like some of the features of Nooks I've seen (such as page numbers), and, if I'd been using their website longer, I might not find it so confusing. But, by and large, I'm pretty sold on Amazon.
So. If you're reading this and you like B&N, Nook and or Goodreads, speak up. Pretend you're a salesman, tout the benefits, and win me over.
