On some Java compile/build benchmarks I did, I got the following:
Test #1:
Laptop P4-M/1.8: 23s (T30)
Desktop P4/2.4: 17s (800 MHz bus)
Laptop P-M/1.6: 15s (T40p)
Test #2 (including much code signing and other nonsense):
Laptop P4-M/1.8: 2m 35s
Desktop P4/2.4: 2m 11s
Laptop P-M/1.6: 1m 53s

(On the T40p) Never tried the S-Video out. The VGA seems fine
for a projector or CRT. VGA->LCD may be good or bad, depending on the
monitor. Using the port replicator with DVI output, an LCD looks
excellent (but may or may not work at 1600x1200).

Well, Intel's releasing the next Pentium-M chip during the week of
May 10. Your guess is as good as mine as to when IBM will release a
machine around it. It took kind of a long time to get a 1.7 chip out the
door, but there was probably less urgency since it was a fairly minor chip
upgrade.

The only hardware I haven't tried with the T40p is the bluetooth
and modem. All the other hardware works fine for me on SuSE 9. I haven't
tried the a/b/g wireless, but the a/b works fine, and I think the same
driver supports both.

I've never seen one, but I've never been to Melbourne, either.
Finally, note that if you order direct from IBM.com, it seems that
you can get a T41 loaded for about $2400 if you "let me build it" -- all
the same stats as the T41p except it would have the 32MB graphics card and
cost like $500 less. Again, not sure if this helps you in AU.
