I've got to admit that I am impressed, too. I got another 2k words done yesterday afternoon. Now, instead, of me typing my story, all I do is tell my story and the computer types for me.
I purchased the preferred program because it gave me the option of reading it back to me. I can't tell you how many mistakes I've caught just by hearing it. Oh, it even puts commas and periods where they belong.
Price was a little steep since I'm no, Nora Roberts or Kim Harrison, but well worth the money! Looks as if I'll make my deadlines!
