I'm pretty happy with this actually, but still a bit worried. Happy, because for once a company didn't see a perfectly good--but decade-old--piece of software and think, "Gee, this has been around for a decade and it hasn't changed, let's RE-INVENT EVERYTHING!!!" (See: Gnome 3, Windows 8). Thunderbird is stable, works, and does its job excellently; no need to turn a wheel into a square just because it's old. On the other hand, there is still some room for improvement in Thunderbird: Gmail integration is kind of hacky and gross-looking (A "[Gmail]" folder? Really?), it could use better Linux desktop integration (notification icons, OSD bubbles, etc.--all of these kind of work, but in half-assed way, I've found). And of course, the ever-important security updates. Even stable software needs security updates on occasion, and someone has to provide that. So with that said: kudos to Mozilla for not undertaking change just for the sake of change like so many other big software projects have of late; but I hope Thunderbird gets just a little more polish before it's placed atop its permanent pedestal, and I hope someone sticks around to keep it secure for its second decade of life.
