Not to get all Apple-apologia, but my wife’s old Macbook is still going strong for casual use (email, video streaming, web browsing) after nearly a decade.
Not really a badge of honor or anything, just that it takes a lot to bog down even substandard out of date hardware to a noticable degree if you don’t do a ton on it in the first place.
I personally like the aluminum case. It keeps them alive longer than plastic laptops.
On the inside its just like any other laptop except more solder points between the components (I used to do repair work on them). And they can sell more used since everyone wants to pay the apple tax.
The Framework laptop the fox talks about is also a metal case. With captive screws and easily replaceable/upgradeable components - and several generations of upgrades already available to build trust that they really do intend to support that upgradeabiliy over time.
