Hi, I'm currently wavering between buying a Nook Touch and Kindle Touch. I currently use a 1st gen Nook and, by far, it's best feature is the PDF reflow. But it's kind of old and I was looking forward to something new. I definitely want an e-reader, not a tablet. Also, I have a loud commute on the train so an attached music player (I hate the one on my phone) is nice. And the vast majority of my library is made up of simple text PDF ebooks (just basic books) so PDF support is important and it also means I don't have a lot of attachment to either of the stores.
I've narrowed it down to the NT and KT but can't decide which one to get. The NT has really good PDF reflow but it doesn't have a music player and I don't like it's hardware (the matte plastic all the way around feels cheap to me and it's very square-like, not much like a real book). The KT, on the other hand, has a music player, nice hardware (shape and material), the special offers, and I'd get Prime benefits. However, lack of PDF reflow makes me skeptical. I am well-versed in the use of Calibre but I know it doesn't work 100% of the time and I don't want to miss out on any of my books (most are older or less known books not found in the Kindle Store - I like weird fiction

). I've heard of Amazon's conversion service via e-mail but was wondering how that works. Is it free? How do the books get on my Kindle? Can I send more than one at a time? How good is the conversion?
Sorry for the long post, but I'd really appreciate any advice. Thanks!
