Oddly enough, both categories are my main computers.
Newest (age): iBook G4 1.33 GHz 1GB RAM/Leopard. This was my first Mac actually, I got it when I switched back in July. Ah, How I remember how happy I was when I handed teh check over to the seller... *wipes eyes* Anyway, this computer I use at my Mom's house, where I'm lucky to get half an hour of time on the computer a day. It's mainly used for web browsing and iTunes.
Newest: (when I got it): 867MHz PowerBook G4. 768MB RAM, Tiger. I got it.. let's see.. five days ago. I use this computer as my main machine over at my Dad's house, where he is way more lenient, computer time-wise. it is used for messing around with Photoshop and Skitch, browsing the web, iTunes, email, and video editing my really crappy youtube videos.
