This is pretty cool - I used Thunderbird for a very long time and tried the beta out briefly. Don't count out Outlook 2010 though...it has some pretty solid improvements too. I can't stand the conversation threading in Outlook 2007 or Thunderbird 2, but the way Outlook 2010 does it is pretty comfortable for me.
