This is MacRumors. Almost every thread morphs into the PPC/Intel sniping contest.
Except that the whole PPC vs. Intel discussion is moot. It's pointless. It solves nothing and nothing will come of it.
The solution is simple, really. If you've got a 3+ year old PowerPC, stick it out for another year with Leopard and enjoy a solid, mature OS, or just buy a new machine now.
Once Apple switched to Intel,
the writing was on the wall. Those people who chose to hang on to their PowerPCs were going to get cut off sometime. But PowerPC machines continue to work, just not with the newest, shiniest OS, "only Leopard", which is still far better than the alternatives.
To understand some real benefits of leaving PPC behind, just consider the fact that point updates of every version of OS X have had to test updates for multiple platforms, but no more. Wouldn't it be nice for Apple to have the flexibility to get critical updates out the door more quickly? System updates that are potentially much smaller? Focus on fixes for Intel only, without distractions for such disparate chipsets? I'm totally in favour of the shift. The diminishing percentage of active PPC users is not reason enough to hobble future development.
The thing is, most (not all) PPC processors were not 64-bit, and most were not dual-core. Even if Apple were to rewrite the core applications for 32-bit, there would be no benefit to Grand Central or any of the other 10.6 functions. The difference between Leopard and Snow Leopard is based on using these differences under-the-hood. For Apple to build a version for PPC, even for the dual core, 64-bit versions, there would not be any substantial gain in performance anyway.
It is just not worth supporting a discontinued (years ago) architecture. Especially in light of the fact that SL needs to be as fast, as lean, and as efficient as it can be. And especially NOW, amid all this apparent competition. Google's OS looming just over the horizon, A Vista that finally works as it should (well, we'll see), and the continued presence of Linux.
A "next-gen" OS has no business supporting an architecture that has been discontinued years ago.
You can still get very good money for G5s on ebay, however. Late model dual G5 towers are still getting around $1000 or so. That's not half bad - proof that Apple hardware holds its value pretty well and that there are people out there looking for the old stuff.
