Not a reply to anyone in particular, just a general thought.
Regarding the whether Apple solders RAM and storage b/c it improves reliability/size/weight, or because they want to make more money (or, perhaps more accurately, is taking advantage those design decisions to make more money): It doesn't have to be one or the other; it could be both:
1) Soldering RAM & storage likely improves reliability. The fact that Consumer Report's annual independent survey of its members finds that Apple's laptops consistently have the lowest average failure rate of any brand supports this.
2) We know Apple prioritizes smallness and lightness in their portable devices, and soldered RAM and storage helps them achieve this.
3) The fact that Apple clearly overcharges for added RAM may indicate they are taking advantage of the fact that it is soldered to increase their per-unit profit. I say "may" because they also overcharge for RAM on the iMac, and there it is user-replaceable.
With storage, it's harder to say. The RAM they use is generic in terms of performance. But that's not as clearly the case with their SSDs, which have provided exceptional performance; so perhaps they are sourcing especially expensive parts for those.
