Probably belongs in a tweet, but since I blogged about it here, I'll write it here.
Stopped using Thunderbird. After it consumed 20 Gigs of space downloading my email, constantly kept my CPU at 80-100% and the hardware fan busy, consuming 500 Megs of RAM... I ditched it and went back to Gmail on the web.
It did have some very nice features, however, basically, I am just over client email programs.
That is all, you may return to your regularly scheduled programs.
