Slow Macs, iPhone. I'm stumped.

All 3 of my primary Apple machines have sudden, inexplicable slowness. My Quad G5, my PowerBook G4, and now even my iPhone suddenly have serious performance problems for no reason I can determine. I know there are some Mac guys on MeFi, I thought I'd ask for additional angles to investigate.

My biggest computing problem is my PowerBook G4 is behaving strangely. I have a PowerBook G4 1.67, 1Gb RAM, 30Gb drive (12free) and an upgraded, faster video "card" with more RAM. it's not the fastest machine on the block, but plenty enough power for basic web surfing, youtube videos, etc. But suddenly, program windows take 10 or 15 seconds to switch, this used to be instant. I run a CPU/Disk meter
and it isn't showing a high demand on the CPU (maybe 30%, like idle) or any disk activity (none) that would indicate virtual memory paging. As far as I can tell, the computer sits there hung for no reason, between almost any switch of display window (whether in the same app, or between apps). I run a terminal command of to look at active processes, and I check the MacOS console logs, nothing out of the ordinary seems to be occurring. And yet, the machine can't even switch windows quickly.
This is most frustrating. Now I know the PbG4 is no speed demon, but it has always performed well, until now. If anyone has ideas on what to examine on this OS, let me know. Otherwise I don't know any way to fix this sort of problem except an archive & reinstall. Hell, Macs (even the old PPCs) aren't supposed to get "Windows Rot" and require periodic OS reinstallation.
Now my Quad G5 (with an QuadroFX4500 video card woo hoo) is exhibiting strange slowness too. It's has enough brute force to deal with most of the tough jobs you can throw at it. But now, I can barely play the average routine YouTube, Flash video runs with freezes and stutters. I am baffled. I upgraded to all the latest PPC Flash, yeah, they suck compared to the PC Flash drivers. Still no improvement in performance. Any ideas?
Now worst of all, my 1st generation iPhone is now acting strange. Switching tasks, like opening native apps like the Timer or the Calendar can sometimes stall out and take 15 seconds. Then other times it's normally fast (considering it's the slowest iPhone model, the first). AFAIK there is nothing I can do about performance. What should I do, restore to factory defaults and reinstall? Jeez, no matter how crappy a cell phone I had, I never had to reformat and reinstall.
So this is my first AskMeFi, I hope this hasn't been covered (I searched) and that this is an adequate format for a question. Dammit I am just baffled, I've been agonizing for weeks, trying to diagnose and fix this slowness but I am just stumped. I would appreciate any suggestions.
