I recently set up a G3 450 iMac for a client with 512 mb of RAM, I installed OS 9.2, Photoshop 5.5, Illustrator 8, Flash 4, and Dreamweaver 3. In addition to be much better suited for the slower processor, these programs are much simpler to navigate for novice to moderate users. After setting the machine up and putting through it's paces I almost missed the simplicity of the 9.2 versions of these industry standards. All of these versions will run great on a G3 450 (close to the top of the line when these programs were released) and will love 192 mb and the older Rage 128. The files that you create can be opened in any later version of of said programs and when you upgrade your computer, processor and applications you can take your files with you. I know that 9.2 isn't as sexy as Panther, but from a production standpoint you will still be able to create professional results that are cross OS compatable, and will keep you from having to spend a bucket load of money. Even if you decide to go with OS X for the iApps, etc. I would suggest considering these older versions of design software that will open in "classic" mode, you will find that they run much faster on your machine. If you must go with OS X.3 and Adobe CS or Macromedia MX then a CPU upgrade will keep you from pulling your hair out. For the record, until recently I was running a G4 500 with 1GB of ram using X.3 with all the latest Adobe and Macromedia and it was sloooow.....
