A handy tool... I save my drafts in .rtf, then load them to my phone via dropbox.
I recently found a text-to-speech reader called Ivona. Lets you download various readers with various voices and accents, so you can have your phone read to you without it sounding like a Stephen Hawking bedtime story. Hearing your work read to you is also a great way to spot typos, poor word choices, double-words, clunky dialogue, etc.
So it's a free and easy way to have your stuff read to you while at work, or without dragooning a friend or family member to read to you...
