I would certainly prefer waiting for a future architecture switch using a 2.5Ghz G5 instead of a 1.5Ghz G4. G5 port can be done much quicker than x86 (as it already runs on G5 machines and runs current PPC software) and x86 port may take quite a lot of time.

I don't feel hurry in switching to x86, perhaps ex-morphos users like Leo&SoundSquare think it's very urgent to switch to x86/ARM but IMHO it's easier and faster to support G5 and then prepare the architecture switch. Then I won't mind if the switch takes 5 years because I'll have a lot of hardware to play with.

Those who feel that jumping to ARM/X86 is mandatory can start using AROS. I think ARM is worthless for desktop, if I cared so much about power consumption I would simply use a programable calculator. I prefer a nice i7 over any ARM thingie any day.
