Comment on Thunderbird

Mail failed to quit and ate 100% processor for the bajillionth time, and I finally switched.
And WOW, is this better than everything about it sits happily and smoothly in my dock 24/7, where had quite a few quirks and outright bugs.

I tried to switch to Firefox, but until now it's been noticeably slower than Safari. Now... I may finally switch that as well.
