This works well if your text document is formatted well for your ereader. By "formatted well" I mean that the only CR/LFs are between paragraphs. This lets you change font sizes or rotate the book 90 degrees and your ereader will be able to break lines where needed for best display.
However, there are lots of text format books that are not formatted well. These usually have a CR/LF break at the end of each 80 character line, i.e., not at the end of sentences or paragraphs. To get these to convert well, you should check "Assume print formatting", not "Treat each line as a paragraph."
