Anyone know what IBM Embedded ViaVoice does? is if diferent than what is in the Z1 today? I have noticed that the Z2(http://presszoom.com/story_124241.html) will have this feature. Will this be available in the Z1 to Z2 upgrade?

It's text-to-speech and voice recognition, this would be software based, so it should be... or I hope it will be, on the upgrade discs

If you have a Pocket PC PDA, you can tryout ViaVoice. I have it installed on my iPaq and it works well...not perfect.
