I was expecting it to be a complete horror-show on my G5 mac, but it was actually really smooth (once it had settled down of course..). Really nice work. Well done!
How many G5 (or other PowerPC based Macs) are still out there, you think? I am working on an App, and debating whether to go through all the trouble to make it compatible with PPC architecture for the first release.
I dropped PPC a few years ago and nobody has complained. Mind you this is scientific software, but it has a few thousand users around the world.
PPC? It seems that few are even supporting Snow Leopard any more.
