I have now installed and used on my iMac G5 and it works great. It's much faster than v7 and much nicer to look at. I have now installed on my MacBook Pro (C2D) my iMac G5 and my Mac Mini without any problems or crashes mentioned by others here. The only problem I have had is that it does not work with Firefox which is not a big deal for me. I have also installed for my virtual win xp install under Parallels and that also works great.
I really like the changes to the interface. I hope CS3 is as big an improvement as this is in particular... **speed**.
I don't get why it is such a big deal that this is not a Universal Binary. At least it keeps the size of the binary on the intended machine down. It is still 100MB!
