Firefox, Thunderbird (occasionally), Winamp, Gaim, uTorrent, Winzip, Acrobat, Ghostview, VMWare, SSH. Netbeans when I need to do work stuff, and IE for testing browser compatibility. MSPaint for quick graphic edits, and Notepad++ for quick text edits. Occasionally Civ3 or SimCity 2000 when I feel like playing a game, and the DVD burning software that came with the machine. Nothing else.
