The first call I made was to my wife, and she sounded like she was next to me. I was blown away by how clear the speakers are - both the earphone and speakerphone. I'm very impress. I'm very satisfy with the 8320 so far.

Things I miss on the treo is voice record feature - actually recording a phone conversation. I also had a freeware on the treo called Call Block, used to block out telemarketers.

The down side on the BB8320 I found so far is the length of time it takes for a reboot. I don't really time it, but it seems like it's even longer than the treo.

It's between 1 and 2 minutes. Seems like a long time but really not. I'm guessing you do it less often than on your Treo!
