Cute. It's also wrong in another way. If you cut a board in half you
double the cost to manufacture. That includes everything involved in
building the board such as procurement, inventory control, handling,
packaging, mounting, interconnect, inspection, etc. This is why
single board computers are more popular than plug-in conglomerations.

The choice solder also makes a minor difference. RoHS Sn/Ag/Cu/Sb
solder has a resistivity of 1.21E^-7 ohm.m while Sn/Pb eutectic solder
has a resistivity of 1.45E^-7 ohm.m. While a 17% change in
conductivity may not seem like much, it makes a hell of difference
dealing with ground bounce problems when the 1.4V i7 CPU might draw 65
amps on peaks. Most of the traces are copper, so that had to be
beefed up, but the typically crappy soldering also needed thickening.

And no I dont want to start a windows vs mac debate.. They both have their

Aw, you're no fun... I might as well throw in some flame bait.

In Dec 2009, I threw together a spreadsheet comparing as near
identical offerings from Apple and Dell. See:
<http://802.11junk.com/jeffl/crud/Mac-vs-PC.xls>
Except for the 13" MacBook, the price of the Apple products is about
twice that of the Dell offerings. Obviously, things have changed
since 2009, but since it took me all day to throw that together, I'll
wait until I catch a cold or have some time to bring the spreadsheet
up to date.

Since this is a repair newsgroup, I might mention that many Apple
products are impossible to repair. Tearing apart the latest mice and
aluminum keyboards will guarantee its destruction. Disassembly of
many computers are also difficult and require much prying and
swearing. I now carry a putty knife for the Mac Mini, and a roll of
mylar tape to reassemble the iBook. The ancient Mac Cube is full of
proprietary and nearly unobtainable screws. Opening an iPod, iPhone
or iPad is rather tricky, until the tricks are learned. Basically,
Apple products are designed to be non-repairable.

Nope. The only mice around here are PC mice. See trophy collection
hanging on the closet door in the background. Unlike Apple mice, PC
mice don't stink.

Hardly noticeable, but maybe what he means is that by designing more

inclusive circuit boards and thus reducing the need for cabling you do
gain some advantage.

That's the only thing I could figure. If you make a trace 1" long
instead of 2" long, the electrons can sprint through it twice as fast. A
nanosecond is just under 12".

I don't know about Apple computers, because I don't work on them, but I have
to say that I find iPods very easy to get into, and all of the major parts
are available from multiple sources at what I think are remarkably sensible
prices. Just last week, I bought a replacement LCD assembly for a Classic,
and it was Ł10.20 (say $15) including tax and delivery. I got it from my
usual supplier here in the UK, and it looked as though it was a
factory-original part.

into, and all of the major parts are available from multiple

last week, I bought a replacement LCD assembly for a Classic,

Your good fortune might simply be that there are so many iPods around that
3rd parties find it profitable to manufacture replacements. The fact that
you /did not/ purchase an Apple part -- for whatever reason -- doesn't say
much good about Apple.

I might also dump on Palm. After seven years, I had to replace the
lithium-ion battery in my Tungsten T3. Palm has illegally abandoned this and
other PDAs, so I had to go elsewhere. Prices were all over the place, as
high as $30. (You used to be able to get the battery and its installation
for $50 to $60, but no one seems to be doing it any more.)

I settled on an HQRP ("high-quality, reasonable price") battery for less
than $7, shipping included. It was surprisingly easy to replace (I expected
tsuris), and appears to be better (or at least have higher capacity) than
the original. Time will tell.

T3 batteries are all over eBay for about $6 including shipping.
<http://shop.ebay.com/i.html?_nkw=palm+t3+battery>

As I understand it, manufacturers can designate parts vendors as their
official supply of spare parts and service. There are also no
restrictions beyond the vague "reasonably priced" requirements that
spare parts be available.

Palm E series PDA's are easy to disassemble and replace the battery.
Previous incantations (i.e. Palm III, V, etc) are nightmares from
hell. The Palm V has to be disassembled with a heat gun.

Incidentally, I have a spare T3 that I'm not using. Also, some E, E2
and E3 units but in not so wonderful condition. Make me rich and
you'll have a spare T3. Contact me via email.

In order to get into a iPhone 3G, you remove 2 small screws, place a
suction cup on the glass front, and pull. The battery is soldered in
place. Furthur disassembly involves removing glued components
(including the battery). It's not impossible, but it's certainly not
easy. The previous iPhone 2G required using a plastic "spudger" to
pry the off the front.

Various teardown instructions:
<http://www.ifixit.com/Browse/iPhone>
<http://www.ifixit.com/Browse/iPod>
However, for real entertainment value, try replacing a broken power
connector on an old iBook G3. I have one of these and was not
thrilled with the approx 50 step procedure.
<http://www.ifixit.com/Device/iBook_G3_12%22>
We can debate whether such inconvenient disassembly is justified by
the allegedly improved cosmetics. My position is that it's not, as
demonstrated by other cell phones and PC laptops, most of which have
user accessible batteries.

and it was Ł10.20 (say $15) including tax and delivery. I got it from my
usual supplier here in the UK, and it looked as though it was a

Good price. It probably came directly from China from the same
factory that supplies the displays to Apple. I get quite a few parts
that way through Hong Kong. However, there are some parts which are
simply unobtainable new and/or at reasonable prices. Cosmetic parts,
custom chips, and wear parts (i.e. power jacks, controls, keyboards,
touchpads, hinges, rubber feet, etc) tend to be difficult to find.
Most of these I buy from eBay vendors that cannibalize machines and
sell the parts. Without used parts, many of the repairs that I'm
doing would be either uneconomical or impossible. I could not build
the business on purchasing new parts from the original manufacturer.

Hey how do I get my 30 GB Video Ipod apart? It has a .5mm streak going
from right to left in the middle of the screen but stops just short of
the left side. But it is in the backlighting because the streak does not
appear in bright light. So it doesn't seem to be the LCD just the
lighting. Does this sound right? I don't want to mess with trying to pry
it apart and bend it all up but I would like to see if there is something
that can be done first without buying a replacement panel.

No. Backlighting failures usually affect the entire screen, or large
areas of the screen, not single horizontal lines. That's the LCD.
It's too difficult to see the line with a reflected light. My guess
is either a blown LCD display, or a bad connection. It might also be
mechanical damage (broken glass) of some sort as I've never seen a
line go only partially across the display.

Burnt offerings, human sacrifice, secret incantations, and

I agree with Jeff. The problem is most likely the display itself or a
connection to it. They come apart quite easily, once you have got one side
started. there are lots of videos on You Tube. The English on this one is
crap, but the actual video shows it all quite well, except that they don't
show any screws down the sides once you have the case off. There have been
tiny screws in all the ones I've seen, but they are obvious.

http://www.youtube.com/watch?v=UYE9VF-9-kw&feature=related

Trickiest bit I've found is when you come to put it back together, and you
have to get the centre button in the control ring to stay correctly in
place, as you try to get the ring to locate in the case front. Not
ultimately hard exactly, just fiddly, and a bit frustrating the first ten
times that it falls back out ...

Sorry, the streak is not there when viewing by reflected light. Only with
back light. And the glass is not broken nor has it been dropped
or bumped or abused.
