Get Thunderbird

I’ve been using Mozilla Thunderbird (created by the same folks who gave us Firefox… the best browser out there these days) and am very impressed with it. I highly recommend it as a replacement for Microsoft Outlook, as it seems very stable, has an intuitive interface, and has features that Outlook has needed for a long time (i.e. the ability to easily change SMTP servers for outgoing email… this is a big deal for anyone who does most of their interneting from wi-fi hotspots)
