> What I'm adamant about being able to upgrade is my software. The big problem with the apple ecosystem is that, while they've been pretty good about it, you are still at their mercy to receive regular software and operating system updates. Once apple is done with your hardware, that's it, you own an insecure brick.

The insecure bricks hold their value weirdly well though, so if you care about the software limits, you can just sell at the end of the term to someone who doesn't, and it makes up for you not being able to keep the hardware longer yourself. Like I just sold off a low-spec 2012 macbook and 2013 iPad Air for a combined $140.
