I kinda get your argument, but I look at my 2015 MBP, and I don't really wish it was thinner. I wish it'd had upgradable RAM and better battery life, and right now I especially appreciate that it has a replaceable SSD because it just gave out.
These are all things I care about that are being sacrificed by Apple to improve one aspect I don't care about (thickness).
I'm definitely not the only one who's thinking that, as evidenced by the comment threads here.
I appreciate you not getting on me for being "stuck on words".
On your opinion on RAM - I disagree. I feel like the way memory modules are psychically, they would probably be detrimental enough (thickness, keyboard, battery, maybe eventual water resistance) that it would out weight the benefits. Besides, you can get enough RAM when you buy the notebook that the amount you get will be good enough far past the date of the CPU being good enough.
On SSD though, I agree. I think with M.2, now with Gen 4 M.2 (and SFF NVMe?), Apple could and should of went to the lengths of allowing that. Even at this thinness, there is not great excuse why not. Besides, its STORAGE. It goes bad, people want to back it up, extract it, recover it, etc. Apple should not have to replace the whole logic board for that.
