I found it to be completely ridiculous. I adore miKindle, but "miGoodness" the text-to-speech seems to be a total joke. When they say it's experimental, they aren't kidding. It really bothers me that it is marketed as a feature of the book. I don't care that it is completely weird and impractical, because I have audio books, etc. to listen to when I am driving or can't read. But, if it had been an important feature to me, I would have been VERY disappointed.
