Question

I am getting a message "can't open because PowerPC applications are no longer supported."  What do I do about these programs?

Answer 1

In defense of the original poster, I just went through the Lion page (http://www.apple.com/macosx/) and the sub-pages linked on the top (including the 250 new features) and nowhere does it say anything about dropping Rosetta/PowerPC compatibility. A simple compatibility line in the tech specs page could help these kinds of threads. Nevertheless, the argument that Apple should have made this change more prominent is quite valid IMO.
Remember that Apple prides itself on being simple so don't expect everyone to be as up to date on compatibility issues as you. With the big uptake of new users in the last couple of years, these kind of questions should be expected, especially since most users are coming from Windows where compatibility is king (I can run apps from 10+ years ago with almost no issues).
Complicating the issue further is that there is no obvious way to see which older applications are PPC and which are not (who knew Warcraft 3 was PPC and not universal??).
A simple solution could be for Apple to provide copy of Rosetta that users can purchase if they want compatibility. Who knows, maybe such a solution is going to come from a third party
