I own an Apple iBook running Yellow Dog Linux, but I do not run a
patched low-latency Kernel, 'cause I use portaudio for my application,
so I don't know much about this.
But other thatn that, it works very well, the only problem I experienced
in the audio world, referred with 'groovit', I was unable to compile it.

Standby-mode and the volume and brightness keys works very well.
External VGA does not work, so I have to boot up macosx when doing
presentations.

 I think this an urban myth, the Nvidia drivers may be proprietary but they

I think this is a pretty rural comment, there is more than x86, where are the
nvidia binaries for 2.6, and personally I really don't feel like loading a
binary only module.

These are also valid arguments but they have nothing to do with the 
stability and quality of the nvidia drivers which is what I intended to 
comment about.

 It looks to me as if Apples laptops are rock solid and don't suffer
 from buggy ACPI to start with. Or is this extra quality just a myth ?

I'm probably getting a powerbook for my next machine - they are well built 
(a lot of people run them at work), the screens are not particularly high 
res, but they make up for than in weight.

The newer ones require kernel 2.6 AFAICT to get the video running 
properly, but that shouldn't be a huge problem. I haven't check up to see
if suspend is working properly - thats a crucial isue for me.

I guess the more of us who buy them the quicker the endianness problems 
will be fixed, ppc-linux-audio-user? :)

I am using a Powerbook G3 500 and a G4 1.25 both with gentoo. They are 
simply great, quiet, cool, powerful (at least the G4 one) machines :-)

The new AlBooks DO have mic-in and line-in again!
Stay away from nvidia on any non-x86 platform, you will never get a decent 
driver for those graphics-boards, whereas ATI-drivers at least offer good 
2D-performance on newer chips and eventually will offer full 
OpenGL-support. (read: ATI is more helpful than nvidia, though their 
support of the dri-project lags a bit behind their 
x86-binary-only-drivers)

Have fun*

This is interesting, I guess you are running the chips with ac97 compatibility 
drivers? 
I've always thought ac97 cards where badly functioning, perhaps times have 
changed. Good to know.

Fan noise, which is very much releated to the CPU power is also something to 
think about. Some laptops are noisy to the point that they are unusable for 
audio-work (or just about anything).

this is no issue for ppc-laptop, at least on my ibook the fan sleep 
almost ever... all the heat is dissipated through the bottom surface. 
the only noise is the hd spin

btw consider that new apple laptops dont have a card with line input or 
so, only a headphone out, and you'll be obligated to buy some sort of 
audio usb/firewire device. i've got an imic, but it dont work with jack 
for format issues, i dunno what.. maybe bit packaging, and the plug 
layer of alsa dont help

and yes, many audio tools are still little-endian-only-
compliant
when that'll change? this is UNIX, we can rack-mount tens of sparc 
doing massive number crunching ;)

I use Dell Inspiron 8200 with NVidia's Geforce4Go (64MB) and in the last
2 1/2 years only had once a problem like that with one particular
release of the drivers. Simple downgrade (and later upgrade to the
fixed drivers which were released promptly resolved that without a
hitch). In addition, Nvidia's drivers, although proprietary, have a
nifty installer that automatically detects the platform and install
proper version of the driver (and/or recompile the non-proprietary
aspects). I heard somewhere that some of the Linux distributions now
ship with these drivers included.

As far as the noise is concerned, Centrino notebooks are now the best
for noise-free high-performance settings. 1.7GHz Centrino notebooks beat
the living daylights outta 2.4GHz P4 desktop in performance, mainly
because they are a complementary mix of P3 performance and P4
scalability. They also offer great battery life (sometimes even upwards
of 5+ hours per battery).

My notebook is 1.8GHz P4 and it rarely kicks in a fan when working with
it. It usually does so when playing highly demanding 3D games. Dell
laptops also have nifty but Dell-unsupported Linux tools that enable you
to control the CPU and Fan throttling hence enabling you to completely
shut them off (obviously if you fry your laptop in the process that is
your own problem). I've used this feature without any problems so far
and the P4 downclocked to 1.2GHz is still plenty fast (although lately
I've been topping off the cpu with my real-time stuff, something that
really annoys me :-).

To give you a perspective on this matter, on the last conference I had
the laptop on-stage with 2 batteries in it charging (hence extra heat
was being generated) set between two pianos. Since my piece was not
first on the program, some bright soul decided to cover both pianos
with the thick protective piano cloth. When I realized this in the
middle of the concert I almost screamed thinking that my laptop would
end up in a pile of smoldering goop, especially considering the fact
that the darn thing was turned on with the power management disabled (I
wanted to make sure that the screensaver or some stupid thing did not
impair my performance) and on top of that charging the batteries. I was
very pleasantly surprised when my number finally came to uncover the
cloth from the pianos and the laptop and realize that my laptop was
completely cool, if barely warm to the touch. Fans never kicked in.

I like Dell for one more reason, their support/warranty is awesome.
Sure, here or there you stumble across a pretty mentally challenged
tech support person that asks you stupid questions and guides you
through the steps that defy common reasoning, but most of the time they
are very prompt (whenever I had to get my laptop fixed, the tech person
would come to *my home* the very next day with the necessary parts, even
if that had to be the whole motherboard and fixed it within minutes --
Disclaimer: I live in US, not sure how it works in other countries) and
helpful. On top of that, when everything fails (i.e. they have no idea
why laptop does what it does), they provide you with a whole new system!
I initially bought a refurbished Inspiron 8000 P3 800Mhz with an old Ati
Rage 4 Mobility (32MB) (their refurbs get a great price/value ratio and
the same support as the new models) and throughout the years when it
broke to the point they had no idea what was wrong, they replaced it
with the current Inspiron8200 1.8GHz P4 at no cost to me. I also was
able to upgrade the video card by myself (from geforce2go to geforce4go
-- Dell has the spare parts division where you can get this kind of
stuff) without a hitch, although this may void your warranty if you
screw something up.

Anyhow, Dell really worked well for me. Some other people were perhaps
not as lucky as me and may have had pretty rotten experiences
