No, i'll move away regardless - probably back to Linux or FreeBSD.
There is nothing wrong with x86. Yes it is an ugly hack of an architecture, but it is fast. And virtually no one programs in assembly language any more anyway, so you shouldn't care what the cpu is like internally.
PowerPC has nothing power competitive.
Intel has the best fabs in the world, and can supply on time and in volume.
Plus, currently i can run any mainstream operating system on my box, at native speed.
Move back to PowerPC? I lose VMware. I lose bootcamp. I'm stuck with Mac OS X (or Linux PPC which is pretty useless in terms of application support) - which, as much as I love the OS, does not serve all of my needs. I use my machine for work.
