All the examples you provided were things excluded because of sheer practicalness. Something was out there that just was a lot better and/or less expensive. To a certain extent, Intel does describe that, but not fully. The Mac Cube doesn't quite fit that, neither did OS 9, but for technical reasons, their days were numbered.
Apple is throwing serious resources at ditching PPC across the board, which isn't necessarily practical at all, and surely not less expensive than just going with the flow. Which isn't to say that the Pentium M is not the best laptop chip out there and they're not justified in ditching PPC for laptops and even a good % of they're desktops. But hey, people will still buy PPC workstations and servers with or without Apple, and Apple offers and sells them and could continue doing so and making money off it. They will, for reasons of keeping they're OS portable, continue a internal port of OS X to PPC for some time so really it's not too much effort on they're part for the OS software.
And no I will not excuse you. Your rude and I didn't appreciate being flamed from the get go, nor it being implied that I am a kook. I wouldn't have replied at all if you'd kept your playground name calling to yourself, because it's become obvious to me long ago that you just drink too much Kool Aid from either Jobs or Intel or both and it doesn't matter to you at all what I say because after all, you ARE so much better than me in every way, right? So hey, chew on that and reply if you must.
I won't be sad if you don't though.
