Most of what I read comes from Project Gutenberg or from here, mobileread.com.
I get the epub version when I can. Then if I need to edit anything, I can. IMHO, chapters should start on a new page and the table of contents should work.
After I am happy with the editing, I tell calibre to email it to my paperwhite. This converts it to MOBI before it sends it.
Now I can read it on my paperwhite when I am home or on the Kindle app on my iPhone when I am out and about. And they remember where I am in the book when I switch back and forth.
Strange, I haven't been using iPhone app much lately, but I have been using the paperwhite a bunch!!!
