Hi Dorsey,
Apple declared EOL for AppleWorks in 2004 or 2005. EOL defined briefly, means Apple would no longer sell or actively support the application.
Knowledge that Rosetta, required to run software written for PPC systems on machines with intel processors, woulld not be compatible with Lion, was presaged by its being an optional install, with the default set to omit, in Leopard and Snow Leopard.
So for those who had been paying attention, it wasn't really a surprise that AW (and all other PPC applications) wouldn't run under Lion. The surprise is more that it continued to run under current versions of the OS for as long as it did.
There's always the danger that older software (or hardware) won't run on newer machines—the Zip dirve I bought to connect to my Perform 6100 couldn't connect with the iMac G3 700 that replaced it. Neither would the 3.5" floppies, or much of the software they contained. Things change.
As for the brainy engineers—they did come up with Rosetta, which kept AppleWorks running for many years past its announced EOL date. I think those of us who bought AppleWorks, or received it bundled with a then new computer, got our money's worth.
Regards,
Barry
