The difference is that with any portable before the disposable Macs you have several options to solve a hardware problem: buy a new component that fits, replace the same component, or upgrade it. The serviceability is gone.
Well, with the new Macs this criticism actually applies only to the SSD (in a lesser sense, as it is principally upgradeable). RAM failures are so seldom that they are not even worth talking about. Battery is fully replaceable in a service centre. Everything else is just as 'disposable' as with previous Macs. BTW, if you have been following the forums closely, you would have noticed that the repair quotes for older MBP and the rMBP are virtually the same.
What I ment to say is that they lose their power over time, as soon as the amount of RAM and storage are no longer enough for the owner needs they loose their power. You are limited to whatever size you originally bought.
In the past I could replace them with higher capacity and sometimes even faster speed.
I agree with you if we are talking about the SSD (I already wrote that I find it very puzzling that Appel didn't use the M.2 spec for the SSDs). RAM is non-issue as there are basically only two sizes (8 GB and 16 GB), both of which are going to be more then enough for years to come. You will not be able to upgrade your 'upgradeable' MBP past 16GB. The times have changed. Few years ago, the machine was usually sold with the fraction of RAM it could usually support. Today they are sold maxed out.
Again, if it doesn't last after 1 year it is a disposable computer. Warranty is one thing, how long the computer continues working is another. If I cannot upgrade it afterwards then it is disposable. Older Macs have better quality.
Again, only (partially) applies to the SSD. Same reasoning as above.
Reduces serviceability and customization. You are locked into your decision today, therefore you can't change your Mac hardware afterwards. It is disposable. Adhesives are a manufacturing and service nightmare.
Again, RAM does not matter - SSD is potentially replaceable. Why do you care about adhesives in the first place? Its not your job to replace it. That Apple can do that for you for a quite reasonable price is for me a good indication that they somehow manage to deal with that nightmare
No need. Just go to the Genius Bar and see what is going on, listen and observe.
All Apple products have had long lists of manufacturing issues. And yet, despite the 'declining' quality, Apple still tops the customer satisfaction surveys.
Apple's design is one thing, the manufacturing quality is another one. However a robust design will not allow for manufacturing defects, a and will not sacrifice the functionality, serviceability and reliability.
I consider my rMBP to be the most functional laptop I ever owned. It is extremely powerful, and yet light and highly mobile, which means I can take it everywhere with me and work under all kinds of circumstances, which is very important to me (scientific research/software development). I don't see any other laptop having more function than this (important: FOR ME)
BTW, my experience is that no Apple (or non-Apple) laptops I owned before come even close to the manufacturing quality to the first-gen 2012 rMBP. The pre-unibody MBPs broke quite easily, the plastic MP started discolouring and deforming before a year has passed.
The real disappointment is the market trend of customers blindly in love with this terrible idea of a "good deal" of buying disposable devices.
Its more convenient *shrug* Again, different machines for different people. You clearly are in a market for a workstation. Apple doesn't make these. For professionals like me which require mobility, the rMBP is a dream machine.
Talking about conjectures. I wonder what a 17" PowerBook / MacBook is?
They have been discontinued years ago - exactly because Apple is all about mobile computing. What they did years ago does not really matter for the purpose of the current discussion, does it? Or would you say that Apple is a printer company because they 'used' to make printers over a decade ago?
That is, what Apple is doing is the same game they did without Jobs and proved unsuccessful.
What an amazing logic

I don't even want to start discussing what is wrong with your argument. Just some food for thought: all current products are Jobs's creations. They were clearly in the pipeline when he was still the boss. The post-Jobs era will begin in a few years.
