You can get Dragon NaturallySpeaking premium at:
In the UK, go here: http://amzn.to/17coVH3
In the US, go here: http://amzn.to/17P9nZ8

I now have a video of version 11.5 at http://www.youtube.com/watch?v=cSbeHJH9sF8

If you want to see how amazing version 11.5 is when using the iPod Touch as a wireless microhphone, take a look here:

Please watch that as well.

I show you Dragon Naturally Speaking Premium version 11 in actual use - you'll see the accuracy of the speech to text conversion live, as I speak.

This is best viewed in one of the hi-res versions.

For a good headset to go with it, take a look at http://amzn.to/kBOdCJ

I'll be uploading a video showing Dragon version 11.5 shortly.
