Just curious. Are you an X86 fan (1978's design), a 680x0 fan (1979's design) or an ARM fan (1983's design) or what?
I don't claim that X86 (or ARM) didn't have many advantages over PPC, but surely "recentness of the design they are based on" isn't among them :hammer:
:hammer: is exactly what the i7 does even to IBM's Xenon PPC derived CPU, the fastest possible remotely PPC derived CPU suitable for hosting an OS.
The first Intel CPU I had any respect for was Centrino Pentium M, Arm was similar to 2:1 advantage per mhz of 68030 in 1987, actually 030 was pretty lame 25mhz 020 and 030 give same MIPS more or less. Point is not only does the i7 wipe the floor with even Xenon let alone G5/G4 but most expensive i7 is cheaper too than the cheapest G4 based SAM board.
Framerates on my games/movies and speed of encoding my own videos are what concern me not emotionally attached to the OS/brand of manufacturer. I hate Windows/Linux AND OOS X equally. I use the most competitively priced hardware with the OS with largest library of apps available.I7 WINTEL. Not the same as when I loved using my Amiga 1000.
Arm is low power netbook/tablet level CPU so why waste money porting OS4 to something that computationally restricts performance. If that's your cup of tea then use AMD Zacate CPU. I suspect you are someone who can't separate x86 (ic 64bit) and Microsoft Windows computer. Same top end CPU and GPU are found in Macs too
It's all about being the fastest and still cheapest price per MIP etc.
