I just opened my old 2001 iBook, running 10.3.9 (2005) with 320 MB of RAM. The Finder was surprisingly snappy. It slowed down a bit once I had an application or two running.
In the dock (on the right had side, vertical) Graphic Converter, Safari, SuperCard, AppleWorks, Claris Emailer, Flash MX, Tex-edit-plus, terminal, NetNewsWire, IE, QuickTime, System Prefs and Classic. There are a few other fond memories in the Application Folder.
I couldn’t get it on the Wifi but it connected via Ethernet.
I was hoping to find out what podcasts I was listening to back then, but no luck, nothing in iTunes at all, I think I cleared out it out at some point to pass on to my wife or daughter.
(My first mac was a performa 475 bought in 1996 just as the power pc macs appeared.)
