I agree with Dj :3. When I get my rig around Christmas, that is what i'll do with the exception of Windows.
I will make a contribution though.
Peerblock - If you plan on doing any pirating, a pain to configure, but nice.
Vuze - Nice alternative for pirating, I hate UTorrent.
Open Office - If you don't get Microsoft Office
Rocketdock - Great for keeping an organized desktop (Picture below from my desktop)
Also, that F.Lux program is magical Yotta, just tried it and I love it.
Ignore that blue blob, I have yet to reformat that button :3.[/b]
