There's a book I'm interested in getting that I could buy in hardcover for $20 or electronically for $10. While I'm generally in favor of physical reading material, this is more of a reference book and I'd like to have it electronically. I don't have an e-reader and would be using the file with my laptop/desktop. My ideal choice would be a .PDF but I'm stuck with a Nook or Kindle format. I know nothing of these formats--is there one version that lends itself to reading on a PC over the other?
