The big reason I'm so harsh on PowerPC is because I really hate proprietary hardware, in general. With so few choices in that market, you just have to take what's there. Hardware is only a means to an end.
What do you mean PowerPC is so proprietary? I guess you can go down to your Local Radio Shack, but some silicon wafers and a few transistors and make your own homegrown x86 CPU? How absurd!
Software is what matters. Why people absolutely kill themselves just so they have the novelty of using "non Intel" hardware is beyond me.
Everything matters, not just software. And people don't go out of their way to buy 'non Intel' based hardware. Some people actually do give a rats arse about the hardware as much as the software. I personally think PowerPC is technically better than x86 (though that's my own opinion on the subject).
Some people prefer commodity over quality... and vice versa! The same goes for some people driving Chevys and Fords, while others are driving Hondas and Toyotas. Preferences differ on what that particular individual requires.
You're short-sighted reasoning above almost contradicts what Amigans have been fighting for all this time. It would be like me asking why are all these Amiga freaks so hell bent on using 'non-Microsoft' software? Because they have a preference on what they believe is a better solution for their own wants and/or needs, PERIOD!
