If you want a repairable computer with a separate chip for every application, I have a coal plant to sell you
What on earth are you wittering on about? That has absolutely nothing at all to do with what I'm pointing out, and pointing out quite clearly enough, but if it helps, here goes:
The Powerbooks and iBooks were just as integrated as the Macbooks. Pretty much every laptop ever worth buying has had highly integrated logic. But in the Powerbooks, you could replace the keyboard by twisting a screw and flipping two latches. In the new one you have to practically dismantle the entire machine to get to it and undo several dozen poppy seed-sized screws.
I've spilt water on my Powerbook, and pulled the keyboard out to dry it. When I spilt water on the Macbook it took over an hour just to get it detached from the machine, by which time it had had chance to fester making it necessary to buy a new one. It was while I was going through this very laborious process that my mind had chance to ponder the pros and cons of the current state of Apple hardware and what attracted me to the company in the first place (of which software was not a major one).
The RAM isn't socketed on the newest machines, and the SSDs use an Apple-exclusive interface. I fully expect them to be engraved with the slogan "Designed by Apple in a disaposable state."
In the meantime, Apple software has become more integrated, better packaged, and generally good all round. Barring a few obvious problems, it's a very solid set of tools. I don't see what this Tumbler chap is complaining about, and I certainly don't see an improvement in hardware.
