Yes, but it is a 'LATIN CAPITAL LETTER O' on the text

Seems that the major unknown is about the SSD controller [1] to know if it uses a custom controller or not. [1] http://www.anandtech.com/show/9173/more-pictures-of-2015-mac...

Look at the size of it compared to the Intel CPU. That thing is huge. What are the usual node size SSD controller manufactured in? 28/40nm

Here's something that might be surprising to some: package size is related to the number of pins mostly, not to the size of the silicon - and more pins if the consumption is higher

(Usually bigger silicon has more pins, and vice versa, but not necessarily)

My understanding is that Apple is one of the leading companies when it comes to eWaste. Also, this is the one of the rare Apple product that that only has industry standard ports/power chargers on it. You can't critique them on building a product that is hard to repair (and wow, this one looks next to impossible for your average non-technician) - but the ewaste/standard charger concerns don't appear to be valid.

Perhaps they are in the leading position, but shouldn't we strive for ever better products? I just upgraded a couple of old MacBooks and iMacs from HHD to SSD and all of a sudden they are usable again - and will probably continue to be so for the coming 2-3 years. That basically extended their lifetimes by perhaps 30-40% and the saved waste is presumably closely proportional to that. So, ideally, I think, all manufac…

User upgrades don't make much difference to the waste. If anything those types of users are likely to have power heavy desktops using up more energy and precious metals. The average user's waste is reduced because the motherboard is much smaller, as well as Apple's general efforts to stop using some chemicals. My first iMac had a warning about mercury in the screen, the second doesn't.

>Apple has opted to transition from using a row of LEDs with a light guide panel, to installing individual LEDs beneath each key. That's progress. Now, Apple, please replace each LED with an infra-red or a visible-light sensor, so that someone can write software to put a representation of the keyboard onto the screen that shows which keys have a finger hovering over them, so that the user never has to look at the key…

I wonder if you could achieve that today with the webcam at the right angle? ;-) it'd be a lot cheaper...

Worth noting that this device, typical for Apple, gets the worst "repairability" score: >The MacBook 2015 Repairability Score: 1 out of 10 (10 is easiest to repair) There are several reasons why this happens; the optimist says that to save space Apple had to glue and solder so much, the pessimist says it's so that Apple can charge more for repairs/replacements.

>But I think both can agree that this generates more e-waste than necessary How so? https://www.apple.com/recycling/ The components are separated for recycling.

> The components are separated for recycling.

Where is that stated? I read these pages and all I could find was Apple saying that Apple requires its external recycling companies to respect local laws, i.e. they are shipping 20ft containers to East Asia and are done with it.

I think it's a combination of optimising for space and cost - every connector that needs to be aligned and connected, and every screw that needs to be installed, requires time and labour. It's far cheaper and faster to glue and solder everything together. This is known as DFM in the industry: http://en.wikipedia.org/wiki/Design_for_manufacturability

One of the more obvious examples of this in laptops is the move from keyboards with shaped keys to flat "island-style" ones; the latter are cheaper to produce.

I'm not sure why this is an issue any more. It was a nice ideal when laptops were just PCs put into smaller boxes, but as manufacturers put the effort and investment into satisfying our demands for smaller, faster, lighter, I don't think the expectation of poking around inside them is reasonable. We don't see people complaining about the repairability of their R-Pis, Chromecasts, SoC systems etc. That's the way hardw…

A big part of the annoyance with Apple is their tendency to explicitly take steps against repairs: insane amounts of glue, multiple "weird" screws (the macbook here uses pentalobe, torx, philips and tri-wing in a single machine), non-standard formats & connectors (I don't expect them to ever swap their non-soldered SSDs for M.2, even though they've altered the connector and format multiple times).

Having the machine be "hard to repair" because it's highly integrated is one thing, taking decisions which deliberately hinder repairability and have basically no other advantage is quite another.

> We don't see people complaining about the repairability of their R-Pis, Chromecasts, SoC systems etc.

Nobody complains about the repairability of an RPi because no specific step to make it harder to repair for no value were undertaken.

It would be interesting to have the Industry Leaders, such as Apple, and Samsung, come out and explain what their thinking is regarding abandoning modular construction.

Even Samsung, with the Galaxy 6, no longer includes a replaceable battery.

My guess, is that in order to increase reliability, and reduce cost, companies have come to the realization that it's most straightforward to do that by abandoning multiple "plug in" components, and just soldering the memory, cpu, flash onboard.

For better or worse, I think the Macbook is the way of the future - and I suspect that in 2-3 years, the vast majority of the laptops being sold will be just a small stick of logic-board+flash+memory in the same way the Macbook is today.

And yet the keyboard alone uses both glue and about 90 screws (https://d3nevzfk7ii3be.cloudfront.net/igi/YYpaGaNumhQuR5M6)
