I am currenty using both a Treo 650 and a Blackberry 7290. On the blackberry I can tell it to set specific messages to a level1 notification. This allows me to have normal email come and do nothing but blink the led. Then when I have an alert from a server, it will come in as a level1 message and vibrate. I do not see this feature in Chatter.

Another issue is, when I go out of service, the net connection dies. This means chatter also dies until I open the application back up to have it reconnect. Is there a way to tell the application to always try and reconnect on its own?

Other than that, it looks good so far. It seems to be as fast as the blackberry redirector / BES setup.
