I have to say nice post.
For me I never felt at home thinking about using or using a kindle. It was the choices Amazon made in how they deal with their books. That was the deal breaker with the Nook. I look at it as I get the best of both worlds, Freedom and control of my content, with the backing of B&N's supply of e-books.
I would normally go for something like an I-Rex or DX, but ruled it out as I have a X-61 tablet for looking at larger print/graphic technical manuals.
