I took my first 'bite' of a PPC-based Mac in mid-2011. It was a 1999 PowerMac G4 (AGP Graphics) 450MHz. Pretty low end machine, but it only cost me thirty bucks. I was mainly into it for the history, and it was pretty useless for anything but light word processing and OS 9 gaming, but by fooling with it I learned that I can make due with older hardware, and save a lot of money (by not buying Intel

).
And from then on my love for PPC Macs and lower-spec machines began.
Since I've acquired that 450MHz G4, I've also bought:
- 1999 400MHz PowerMac G4 (AGP) $20
- x2 1999 500MHz iMac G3's $50 (I sold one of them for cash to buy a PowerMac G5)
- 1991 16MHz Macintosh LC (sold it for cash to buy a PowerMac G5) $90
- Late 2004 PowerMac G5 1.8GHz (latest purchase) $120
Here are the current uses of the computers I own:
- PowerMac G4 450MHz: 90's games (used to be a file server).
- iMac G3 500MHz: A machine I have for kids to play with if friends bring them over, with kid-friendly games.
- PowerMac G5 1.8GHz: Main desktop machine. Word processing, web browsing, 2000's games, file serving, iTunes library, all media purposes.
In the future I plan on purchasing:
-1.42GHz eMac (purchasing one next week!)
-200-200MHz PowerBook G3
-1.67GHz PowerBook G4
-1.8GHz or 2.0GHz iMac G5
-1.42GHz Dual PowerMac G4 MDD
-2.5GHz Quad PowerMac G5
Anyways, I plan on sticking with PPC until they're hard to come by, and decent (2GHz dual core) Intel machines become as cheap as these things are now.
