While I have been using Thunderbird for quite a while on my Windows box and my PowerBook, I’ve finally switched to it on my main work machine. There wasn’t really a reason I didn’t before except for lack of time or laziness, so now we’re converted. I’ve also installed the Calendar extension, though the Mac OS X version is an unsupported build. It seems to be working ok so far, except for importing some other calendars I’ve used in the past. Anyway, onward and upward in 2004, right?
