It's not about upgrading, it's about repairing when it gets broken. Which no matter how well made SSD, batteries or memory is, it will in a few years (at least on average).
If it's soldered on instead of simply connected, that means repairing it requires much more skill, and can easily result in damage to other parts. What it means really is that fixing a broken macbook costs way more then it should if they just used a normal connector.
In the case of this specific example, the fact that the display cables are part of display itself means that "a 5$ repair by replacing a cable turns into a 500$ replacement of the display". Which basically equates to a 500$ yearly subscription on a 2000$ machine.
Ok, this is what I'm looking for. What statistics back this up in any way?
I have a 2010 macbook pro that is still kicking quite well. No issues at all. I'm sure you have some anecdote about some Dell too. But you say on average, in a few years, all laptops will break. Where is the evidence for this?
