Re: less repairable / upgradeable than ever
I do. My 2007 iMac's memory needed replacing two years ago, I used that opportunity to upgrade it as well.
Part failures usually happen at the start-of-life or the end-of-life. If you make it impossible to replace that part, then the end-of-life of that part becomes the end-of-life of that device.
