Adobe announced today that future versions of the applications in their Creative Suites will no longer support PowerPC (PPC) Macs. With Apple’s recent announcement that the next version of OSX (Snow Leopard) will not support the PowerPC chip set, there was really no reason to continue with future development for the pre-Intel platform.
So if you depend on Adobe Creative Suite software for a living but have not upgraded from the G5 or earlier Macs, you might want to consider doing so sometime early next year if you plan to take advantage of all the new features that Adobe Creative Suite 5 will bring.
