Fabulous. I copied tekst from extensive HTML pages I created to the included editor (selected in Safari, than pasted in the editor). The editor is somehow HTML aware, and so is text to speech, I think. Works, is blazingly fast (1 minute to create 20 minutes of speech on my 17" PB).
Now get me this to put an entires week of MacFixit and MacInTouch on CD for my car, without me copying the stuff by hand, and I will come (Web Services anyone? Can we use RSS for this?).

(On a side note: the UI needs to grow)
