what I like about the rollermouse is:
1. My hands stay right in front of me, as if they were resting on the space bar. I could not use a regular mouse because holding my arm out to the side where the mouse was was too much for my biceps and pecs- they were always engaged.
2. The bar rolls and also moves side to side, it feels just like you're using a ball, although it doesn't look intuitive at all. To click all you have to do is push the bar. Or you can use the button right next to the bar you can adjust how hard he have to push hard to click underneath. Like I said, it doesn't look intuitive, but is actually really easy to use, and the finger movements are very small.

As for Dragon. I would offer the following comments:
1. if you put a microphone to sleep and walk away from the computer. It tends to have flaky sound settings when you come back. It took me awhile to learn that the fastest way to fix this was to close Dragon and reopen it.

2. I tried to scroll up and scroll down command, and it still seems to go a whole page that is actually what the scroll up and scroll down command are supposed to to. However, if you say "press up arrow" or "press down arrow." It will only scroll a few lines. There are a lot of commands like that, but there's a learning curve to find out what to say to make you do what you want. There are some things I really can't do with Dragon that I still do by hand
3. The program that I think Dragon is the easiest to use to control his outlook for e-mail. I really like its functionality their demands are very straightforward I can receive and send e-mail pretty much completely hands-free. My web browsing is definitely not hands-free and I do find it easier to use the mouse to go to where I need to correct things. Or add things that I forgot. You're supposed to be able to tell it to select certain content, but I find that it's a little cumbersome. I might get better at it with practice.

Anyhow, that's my thoughts. It's too bad they don't sell a test version.
I would be happy to answer any more questions just keep throwing them at me.
