#Power PC
I'm not sure what will happen – MSoft has an 80k emulator built into
NT for its RISC platforms, and I doubt (except on the really
expensive platforms) that a 2x speedup will happen – but recompiled
apps _will_ run faster, and there are plenty of NT apps coming out.
Not whordes, yet, but enough on the high end to at least open the
door.
As to Macs, 68k-compiled apps will probably run slower on the first
few PowerPC Macs, but I'm sure Apple will manage to pull several
PowerPC recompiled Apps out of the wood-work, and unlike
Clone-owners, Mac people won't have a choice – the 060 is the last
68k chip, so where else are they going to go? I can't imagine that
the entire Mac platform is going to instantly die when it shifts to
another chip.
And what are we going to do when the Amiga shifts to another chip? I
hope not curl up and die. (If I don't get a new one sooner and
assuming nothing strange and unfortunate happens) When it comes time
for me to get a new Amiga I'm not going to get an 060 Amiga when the
entire platform is shifting to, say, Alpha Amigas – 68k apps would
run reasonably fast on an Alpha and as time went by (I would hope)
there would be more and more native Alpha apps.
It's a different game for us (Macs and Amigas) than it is for Clones.
Our chips are drying up.
