I'm just downloading and trying out version 2.0 of TextAloud. This is one of my favorite apps, and ways of making use off all the time I spend sitting in traffic. It will convert files, text etc to MP3 files or speak them directly. The new version offers support for reading html, word and pdf files directly. There is also a new IE tool bar. If you purchase one of the nice recorded speech voices the output can be amazingly pleasant to listen to.
