The SSD will not get soldered to the motherboard, it’ll get plugged in and then a screw holds it in place. Thus, no preparation of merging the board and the SSD have been done.
The reason specified by Eve was that the number of SKUs has to be kept to a reasonable amount (that is why they chose to offer only a small, medium and large set of specifiactions). Every additional differentiation increases costs overall plus might cause timeframes to extend.
So to revert your question back to you - in regards of disappointment - would you be happier if Eve agreed to exchange the RAM to 16GB for you, but that would cause your device to be shipped last, pretty much shortly before the webshop orders start to be fulfilled. Probably you would then start complaining that it is another unreasonable delay, because it can’t be so difficult to just add something as minor as RAM.
Please be considerate of the team size (as we learned in the other thread it is approx. 13 people). They have enough tasks on their hands even without an increased amount of SKUs. You were happy with the option chosen at the time of IGG, and still these three options are all we get. If more RAM is essential to you, you do have an option to increase it by switching to a better model (other than some that would want 32GB, but the CPU doesn’t allow this).
Btw, the SSD upgrade is something they said they will look into, but so far I have not seen a confirmation that that’ll actually happen (the limitation is the availability for the 1TB SSDs).
And particularly how you raise the request, I consider quite presumptuous and not very respectful.
