Sorry Paul,
You mean, "Sorry Steve:-)"
but I've changed hard drives and RAM (as have many of my
non-computer-industry friends) on those exact models. I've changed
them on ALL of the laptops I've had, both my own and many pre-prod
units.
Apple puts its own label on the drives they use as OEM and you might
not find the part number for that OEM unit in a Hitachi or Western
Digital list, but that doesn't mean the drive units are not industry
standard equipment. I've changed out the drives in virtually ALL my
systems (for larger ones) as it has always been less expensive to get
a lot of disk space that way.
I've changed drives in most of my Macs as well. It was more difficult
on the powerbook G3, but not terribly so. The G4 chrome desktop was a
bit tricky as well, and you helped me find instructions for thatt.
But most of the time, it's been quite simple.

RAM and hard drives have *always* been user upgradeable, on all of
them, although some have been easier to do the upgrade than others.
i didn't work at Apple, but i have direct experience replacing hard
drives
with several of these models, and a lot of knowledge of Apple
policies and
hardware ... for laptop hard drives, what you say is only generally
true for
certain uncommon definitions of "user upgradeable"
all of the g4 PowerBooks and the MacBooks Pro until the Unibody
have had a
deeply buried hard drive -- the vast majority of users would not feel
comfortable with, and might well bungle, the replacement task; but
yes, if
it were accomplished carefully, it would not void the warranty, so
that
meets one definition of "user replaceable"
in contrast, Apple has officially sanctioned the hard drive as user
replaceable in the current Unibody units; the instructions are in
the user
guide (whereas for previous G4 and later laptops no public Apple
instructions are available for hard drive replacements); if you
have good
touch with a fine Phillips screwdriver, you can replace the hard
drive in a
Unibodoy MacBook Pro in less than five minutes, though it still
takes some
care; it's at least 20 and more like an hour the first time with
the older
models
comparison - three steps (numbers 5, 6, and 8 here) are all you
need for the
Unibody models:

They've always used industry standard components for these items
too.
yes and no; the hard drives always (still) have a custom label with
an Apple
logo on them, and the model number often doesn't exactly match what
is
commercially available, though the actual differences from "standard
components" are miniscule because, of course, Apple does not make
hard
drives
