Many laptops offer upgradeable RAM and some upgradeable CPUs. All laptops of my family have upgradeable RAM for instance. SSDs bays and M2 slots as well.
All LiIon batteries are around 80-85% of capacity in around 350-500 charge cycles given a decent controller and no excessive heat (which macbooks are overall bad at).
Upgradeable ram would be the only thing I’d want from Apple. With the advent of Dropbox & similar it’s been a long long time since I’ve run out of disk space. And as I’ve said before, I typically see laptops struggling to perform long before seeing their batteries give up on me.
