Perhaps they have nothing to do more with whatever they have. Perhaps life is is boring with what they have.
Speaking as someone who has a small PowerPC collection but uses Intel Macs, and has disagreed with people recommending PowerPC Macs before...
My biggest issue is that PowerPC Macs typically require more... love, care and attention than Intels. If you know what you're getting into, that's awesome. But I see way too many times someone who doesn't know better, but is expecting the "Mac experience" is recommended a PowerPC Mac to save money.
I wouldn't recommend PowerPCs for that purpose. They can't run the latest software. They can't run normal Flash well. They can't be taken to the Apple store and repaired.
For power users that's ok. But for a recommendation to someone who want a machine that just works, and they can go to the store and buy software for, it's just a poor choice.
I guess my general problem is with people who have the attitude that Intel Macs and PowerPC Macs are for, all things considered, equal. You can throw blame at different parties around all you want, but at the end of the day they aren't.
Still love my PowerPCs as collectors items though. But they're old computers.
