How to export and read .txt files using iPhone? I've some text files (a few thousand lines each) on my PC. How can I transfer them  to the iPhone so that I can do my reading on-the-go?

(Sure I could simply email them to myself, but I'm looking for a more convenient and less time-wasting solution.)
One solution would be to use Dropbox or iCloud to hold/sync your notes and read them with a simple text editing or note taking app. I use Byword.
