Then there's the service manual for the first edition ipad:

Where they describe the sim tray as the only user serviceable part.
FWIW, I have both of these devices and they both work still work fine...
Because of the way apple has locked it down, the software on it can't be replaced with something less broken, even though hardware-wise it is basically a raspberry pi with a touchscreen.

Also, my iPad 2 broke down after a year and a half. Not buying Apple again!
I think it would be great if Apple designed their products to be user serviceable so if something like a screen breaks all you have to do is buy the screen and repair it yourself instead of sending to a repair store, but I definitely don't agree that Apple designs their products to fail.
Pluses: Individual parts are available to order directly from HP. Once you've identified your machine's exact variant, you can get the service manual and replacement part numbers. The actual disassembly+reassembly was (in my case, at least), really easy, with just a few screws.
Minuses: The parts are expensive, model-specific, the correct model number is sometimes confusing to find. Opening the machine can be a destructive operation, for some models. Internal connections don't always use standard interfaces. Close to every model seems to have customized parts, and there are a lot of model variations, so finding second-hand replacement parts is difficult.
As seems to be the usual trend, I'm sure that the business models would be a better experience and the consumer models would be worse.
It took me more than 5 hours to perform a simple cleanup task.
It's not much use giving us step by step instructions on how to service each part when it involves removing more than 60 different screws.
Those things were definitely not build to be serviceable.
I replaced the SSD, wifi card, and repasted the CPU/GPU cooler. The operation took me 30 minutes.
I've sworn of many manufacturers / vendors for crap lines.
If you want to have a quality brand, you're going to have to apply it uniformly.
I have a hunch that can be said for most laptop vendors. There is reason "business notebooks" cost so much more. I'm not saying it's a good reason, but it's there.
