Download : This took forever, I guess all the servers were swamped because my 1megabit cable connection wasn't pulling more than 5k/second.
Install : Pretty standard stuff.
Look and feel : The new interface is pretty, I liked it.
Usage : It prompted me for my SMTP password, which is not cool because I don't remember it and don't feel like bugging my boss.
Conclusion : Re-installed Thunderbird 2.0.0.23
