I have it on my 7100i its pretty good if your driving or not able to use your hands typing. It takes a while for it to process your command but if you can deal with that its a neat little program. I have noticed it will drain your battery a little faster than normal since it checks the status of your battery and other stuff. If you install it take a look at your logs and see how much it takes up. It also is always running in the background as in it never shuts off. I think there is a demo on Nextels home page on your blackberry browser.
