I'm pleasantly surprised/seriously impressed as to how responsive the system is. Safari is teh snap!

Trying it out on the iBook before I try the iMac....

I installed it on my Dual 533 G4 (133MHZ bus and 1GB of RAM and a GF2mx video card) and it runs just fine. It'll make a nice Time Machine server in the basement.

It would also be important to post the PPC model, so that we know if it has L3 cache. Also how much RAM, and as a precious poster did, the graphics card installed.

I installed Leopard on my grandmother's 17" PB 1.67 G4 512MB RAM and it is dog slow. I immediately ordered a 2GB kit from Crucial.com for $60. 512 RAM was getting ridiculous for Tiger. Leopard on 512 is laughable.

The graphics and animations were a bit choppy. Apps opened slowly. Boot times were around 2 minutes. I recommend making sure that Leopard has enough RAM for decent performance.

EDIT: Forgot to post the rest of the specs.

1.67Ghz G4
167mhz bus speed
512 DDR2 RAM (upgrading to 2GB)
120GB 5400 RPM HD
128MB Radeon 9700

I have a mac mini Power PC G4 1.25Ghz, 1GB Ram, ATI 9200 Graphics. I done an upgrade with no problems Sefari is much more snapier and overall i am impressed. The only thing is a few of the options such as quick look are disabled due to the processor power of my mac

I just installed mine on my iBook G4 1Ghz. It's pretty good. All apps seems to be opening at the same speed as before. The graphics are a bit choppy, but that's to be expected. Otherwise, I'm quite happy so far.

quick look shouldn't be disabled.

With the processor and amount of RAM you have installed you should be able to install Leopard without a problem. The performance you get from the system will be subjective.

For a short while I had Leopard installed on my iPod and booted from it to see how it performed. I was surprised by how well the interface responded even when running off a slow drive. A few months later my iPod's hard drive died and I stopped using Leopard. I may install it on my PowerBook eventually but for now I'm still very content using Tiger. I also tested Leopard on my PowerMac and was impressed with the performance. Its definitely not like jumping from XP to Vista. The specs of my systems are listed in my sig, below. The PowerBook has a 167MHz bus and the PowerMac has 133MHz

iBook G4
1.33 GHz PPC G4, 133 MHz FSB, 512 KB L2
768 MB DDR RAM, 60 GB 4200 RPM HDD
Panther, upgraded to Leopard

Leopard is generally fine. Quick Look is slow quite a bit of the time. Thumbnail generation is fine (as fast as with Panther). Finder is fine but sometimes slow. Boot time is ~2 minutes. Average CPU usage is anywhere from 5%~10% to 30%~40%, depending on the applications open and tasks I'm doing.

Safari works well (when it's all in RAM), even with 20~40 tabs open. Scrolling is fairly snappy.

Video playing: Playing a YouTube video makes the CPU go close to or to 100%. YouTube-quality iTunes videos make the CPU go up to 50%~60% or so. When I pause one of those, playing it from pause makes the video stutter and skip heavily for several seconds to a minute with the CPU at 100% before playing normally. Other iTunes usage (version 8) is good. Some iTunes videos will stutter or almost stutter while playing.

iPhoto 4 isn't quite as fast as I want it to be, especially when creating a new album, and at the end of importing photos. The CPU hits 100% for a minute or so after the last photo, then finishes the import.

iWork '08 is slow at opening, saving, zooming, template applying, and just about anything that isn't basic. But it's far from unusable.

The real slowdowns are caused by lack of memory (heavy virtual memory usage), and these are more pronounced with Leopard than with Panther. I agree with the posters who said enough RAM is essential.
