TFF is probably the only place where we're going to get halfway accurate numbers. We don't and won't know how many there really are in the wild, but we might be able to see trends. Each pic represents the "call home" TFF makes to version check. The raw numbers have actually GROWN, likely because of knowledge of TFF (and Leopard Webkit) as a resource. It probably isn't due to an actual increase in PowerPC users--sorry. This pic represents the callback by OS. You'll notice a sliver of 10.6, because some 10.6 users do use TFF. Other than that, it's fairly even between 10.4 and 10.5 users. Soonish, 10.6 numbers will rise, since they are heading into unsupported-land pretty quickly. Percentage-wise, the G3 and early G4 users are dropping. Here we find out how many Rosetta users are using TFF. It's not that many, but somehow the G5 version will run under 10.6. In addition, we get to see the rough percentages of processor vs 10.4 or 10.5. G4 users tend to stay on 10.4. G5 users tend to stay on 10.5. You'll notice on the next graph also, there are impossible combinations, like G3-10.5. It's most likely Rosetta. There's also G5-10.6, which means the G5 version HAS to be running under Rosetta, despite a lot of disadvantages. Finally, we have what version of TFF is calling home. 31 is still fairly new to TFF, but 24 is still the one used most. So what does it all mean? It means we're still using PowerPC, at least on a web browsing front. And that is about eight years after the Intel transition. Personally, I hope my PowerPC Macs never die.
