I am currently using a BTO maxed out PowerBook G4 15" early 2005, and wanted to see what you guys are running. I've included a poll, but you can add details in a message.
12" iBook G3 dual USB 500mhz with 640MB and 10GB HDD running Tiger.
Particularly pleased with the PPC 10.4 port of HoRNDIS that enables me to get online with the iBook when I'm away from home through USB tethering to my Android phone so that it can use the data plan or access WPA2 routers.
Right now, I’m using my 800mhz 12” G3 iBook to mess with The video scripts that @Dronecatcher put together, but I actually use all of the above with the exception of 3 of them...
I occasionally fire up an a1010 pb6,1 10.4.11/10.5.8 but for most tasks, faster machines are used.
Sadly my 17” a1107 pb5,7 died an unceremonious death & has been sitting on my shelf for about 10 months now waiting for a donor logic board or headless body.
I semi-regularly use my 333mhz Lombard, it's attached to the stereo so the recording of LP's is done there. Since it also runs 9.2 it's the backup plan if I ever need to reset the LaserWriter 16/600.
Recently bricked a 15" 1.67ghz model.
