Here's the setup I have at work. I do mostly web production and video editing.
Power Mac G4: Dual 450mhz Processors, 1gb RAM, 119gb HD (30 IDE, 9 SCSI, 80 FireWire), Ultra Wide SCSI card, MicroMotion DC30 plus video capture card, ATI Rage 128 AGP, ATI Rage 128 PCI video cards.
2 Princeton EO90 19" monitors.
Software: Adobe GoLive 5.0 (not very stable, well it's a lot better under OS 9.1, but it's just better that 4.0 that I can't go back), Macromedia Fireworks 3.0 (I've been using this since 1.0 and consider it a godsend), Adobe Photoshop 5.5, BBEdit 5, Fetch, MacSSH (and when that's not good enough, I use MI/X, a X-windows server to connect to the Linux server in the office and use terminals from there), Quark 4.1, Adobe Illustrator 9.0, Adobe Premier 5.1c, Cleaner 5 (another damn cool program, although not as cool with the dual processor G4 because it encodes so fast that a batch isn't as necessary), MS Internet Explorer 4.5 & 5.0, Netscape 4.7x & 6, Mozilla, iCab, Virtual PC, MS Office 98 (powerpoint, excel, word), Norton Utilities 5.0.3, and oh yeah, SoundJam
I think that's everything.
Then I've got lots and lots of little programs that I've downloaded and haven't played much with or are just little quickfix utilities like MacPerl, AutoPurge (is probably not needed under OS 9.1), Anarchie, Kalediscope (what a great little control panel), Gravite (anyone running a Mac should check this out, completely useless, but a lot of fun), etc.
