BTW does Kindle let you load your own DRM-free ebook files instead of buying books on Amazon? I use a PocketBook (pocketbook-int.com) which emulates a mass storage device and lets me read everything. I once considered buying a Kindle but heard it won't let me load bare files this way. Is this true?
The only functionality issue I run in to is that as far as I can tell, Amazon has a feature where if you buy the book from them then they keep your progress synced between your kindle and their phone apps. Can't use that with books from other sources.
