Hello all, it seems like older Macs *will* continue to be supported in OS X
10.3 (Panther), and that Panther will be *faster* than Jaguar.
This means that we'll be able to use our old G3s (and early G4 towers) for
at least another two years with the latest OS. I was half expecting Apple to
dump any computers with less than 16 MB of video RAM from their supported
list but I guess that worry wasn't realised :) :) :) (it makes sense to
ditch the smaller video RAM models since a poor video card kills OS X
performance far more than CPU speed). I guess as long as they still are
selling the G3 iBooks they'll have to continue supporting the G3 CPUs
(especially since the iBook G3 is in effect no different from say a Pismo
G3/400 except for a little extra video RAM (less real RAM), speed and can do
AirPort Extreme as opposed to AirPort (yippi ay yey... 11 Mbps can
outperform a 1.2 Mbps ADSL line 8 times over so having 15 Mbps (802.11g does
not actually run at 54 Mbps) isn't going to make a difference).
PS I'm still trying to prognosticate on where the next hardware break will
be:
System 7.0 2 MB RAM was the breakpoint (1992)
OS 8.1 68040 was the minimum needed (1997)
OS 8.5 PPC only (1998)
OS 9.2/OS X REAL G3 only (no G3/250 laptops) (2001)
OS X 10.4 G4 only? video RAM? G5? No dual boot?
I see two possible shifts ahead at the moment -- either the no dual boot
option (they've changed hardware enough), or G5. G5 seems the more logical
route but that means that computers currently supported by OS X will
probably be supported at least until 2007. Perhaps there'll be a smaller
revision dropping sub-256 or 512 MB configurations, or dropping smaller
video card support.
Anyway, I'm happy with this report since I'm running that exact same laptop
(0.5 GB RAM vs 1 GB RAM though).
Eric.

Subject: ....benchmarks of Panther Preview on Pismo
Thought you would be interested in seeing some Xbench tests of Panther
Preview vs. OS X 10.2.6. As you can see below, Quartz is now supported on
the Pismo (ATI Rage Mobility).
Installation:
Installation was perfect, no problems. New Finder, Expose, and FAst
Switching worked well. Only hitch, the "cube-effect" didn't work on the
Pismo during Fast User Switching.Perhaps, its not supported on the Pismo
yet.
Pismo Configuration: 400MHz, 1Gb RAM, Toshiba 40GAX
Panther Preview
Results: 42.68
CPU Test: 45.60
Thread Test: 35.05
Memory Test: 32.84
Quartz Graphics Test: 50.85 (Supported at last!)
OpenGL Graphics Test: 38.64
User Interface Test: 66.93
Disk Test: 44.20
OS X 10.2.6
Results: 32.88
CPU Test: 33.07
Thread Test: 24.61
Memory Test: 24.62
Quartz Graphics Test: None (Not supported)
OpenGL Graphics Test: 35.49
User Interface Test: 38.25
Disk Test: 59.92
Observations on Pismo:
Quartz is now supported on the Pismos (ATI Rage Mobility)
Panther is about 40% faster on the CPU tests.
User Interface is over 50% faster than OS X 10.2.6!
Only test where OS X 10.2.6 does better than PAnther is the Drive Test, over
30% slower than OS X 10.2.6. Probably due to Journelling. I'm sure this will
speed up with final release.
Only have to say one thing, this Panther Preview rocks bigtime!
