If this app can do this it can turn a text file into a readable document for eBook readers.
There are also some coded conventions used by Project Gutenberg to encode italics, bold, breaks in txt etc. into a txt file. If this converter can recognize those conventions it can also be useful in converting books.
My point is that a reading app could do exactly the same tweaks on the fly, there really isn't any need to convert to a intermediate file.
However, this clearly isn't an important enough point to warrant all these posts, so I shall stop
