Sound and Volume work well for me. I also had the 6700, but I never experienced any trouble with the volume or sound for what it's worth.

The form feature is definitely the best and can't be beat.

For the first time in many years, I actually feel like I have a real cell-phone, not some huge pda with a cell-phone built-in. And still, I have access to mail exchange server account, the internet, and other items that come with a pda.
