I have some thoughts about Marble and why it didn't make it into 10.6. Since they're cutting off PPC upgrades with this version, it makes sense to make it as painless as possible. They left marble out so that PPC users wouldn't feel like they're being totally left behind. I imagine the outcry would be far worse than it's been if the entire OS received a major overhaul.
Outcry? What outcry? You mean nerd-rage that only happens on tech forums that the average user has no clue about and doesn't even care about? We represent a hopelessly small minority, and our assumptions about what's good and bad about SL is in no way necessarily true when the average user brings it home.
"Marble" is just a rumour. It's vapour. It was never officially announced for Snow Leopard. It was something John Gruber "heard" from an "independent" source. It was a prediction. If it somehow, miraculously makes it in to the full release, great. But it has nothing at all to do with PowerPC or PowerPC Mac users.
The attitude about PPC at Apple is much like Steve Jobs' attitude about old Macs in general: it's finished. Forgotten. Done. It's
dead like QuickDraw GX. Jobs would gladly forget all of the PPC years if he could. The real "Flowering of Apple" in our time occurred when Apple moved to Intel. PPC was left behind three or four years ago. There is no point in pleasing PPC users when the entire organization is working with a completely different architecture, wanting to push the Apple/Intel paradigm. Apple no longer sells PPC units. Discontinued. Why on earth should they continue to develop for them???
"Feelings" have no role in this. Apple PPC is legacy-ware. Apple wants you to get into Intel, not to give you an excuse to hang on to your PPC. Then again, there are many users that are perfectly happy with their old Macs as they are. All this angst over Snow Leopard being unavailable for PPC users lives and dies on these forums. The rest of the Mac userbase could care less.
Did you see people at WWDC booing SL's lack of PPC support? Did you hear or read about it? Do you see the newsmedia going crazy over the issue? Do you see tech blogs moaning about this? We all know that bad tech and lousy products get what's coming to them, like the tons and tons of bad press Vista has gotten. Vista has become synonymous with "flop" and "failure", and Apple rightly plays on this. Meanwhile there's a huge chunk of the Apple userbase that doesn't even know what "PowerPC" is, and who probably wouldn't care to know anyway.
