IBM had problems with their design which was why they teamed up with
APPLE. at the time theirs was the worst performing and selling. Don't
forget Motorola was in there too, coming in especially with the G4.
Sun and SGI always had the better designs in the 90s but pricey too.
Nevertheless SGI cornered the movie business and Sun the web server
market. The g5 got apple into the big time.
But I think that they have blown it now. Intel centers on the lower
end of the market now with their low power cpus. For high end machines
clearly IBM and AMD excel. These are the cpus preferred by scientists
and engineers -- they are not the same as the consumer versions
admittedly but those benefit from this research. I know Bruce will
argue with this but I am speaking statistically of course.
Clearly apple is a consumer company. Although the video industry
helps, many specialists have complained the intel macs are not so good
for them as the g5 was. (Intel centric) Benchmarks aside, this is user
experience.

Its an old story in the computer industry -- once you finally get
something working right its time to abandon the manufacture (except
for the embedded systems I guess). Finally in the last few years we
have seen altivec based libraries for c and c++ and in gcc4.3 the auto
generated code really took off.
(unfortunately apple is still getting into gcc4.2).
When I get the time I would like to rebuild a linux system from
scratch optimized for altivec...

gaming consoles, selling a million a month.
(and other things).
IBM also sells intel based machines, but their POWER
are their best.
By the way they have POWER5+ intellistations on closeout for $5000.
2x2ghz dual core, 4GB RAM, 32MB Cache on-chip, dual SCSI drives, and
free monitor.
(G5 is Power4). No OS. Put Linux on and run Leopard with MOL.
Or you can try it on a PS3 except I don't think the RAM capacity
suffices.

It was true back then. Problem was all the old 68k code in the old
MacOS. Back in '98 a mac with Linux felt like flying compared to the
macos crawling.
IBM was like I said at the bottom of the RISC mfgs. Motorolla had many
delays in their 68060 development and they really needed the g4
business.
Even today a dual g4 can be as good or better performer as intel dual
core in certain applications (such as with g4 upgrades versus current
mini/ imac models = clunky consumer junk)
