What does that mean for existing Palm software - will it be like when
the Macintosh changed from 680X0 to PowerPC? In that transition, there
were three flavors of software:
(1) Written for the old chip - run native on old machines, and in
emulation on the new machines (at some efficiency cost)
(2) "Fat" (both types of object modules in one file - run native on
either old or new chip, but memory bulky (leading to "stripper"
utilities to get rid of the non-useful one on your machine
(3) Written for the new chip - fast and efficient on the new chip,
but would not run on older machines.
In particular, I get the impression that Chess Genius for Palm is
680X0 assembly, and Tiger is largely in C, so I would imagine it
easier for Tiger to take advantage of this change than Genius.
(Unless Richard has ARM assembly engines around, which he might).
