Interesting question.

I never worried about the CPU, even overclocked not surviving me by decades.

My concern is about the "hard disk" , it must have a certain limitation in write cycles it can support, no?
Especially with heavy swapping going on.

32GB is still standard today, and Nokia generously provided it in 2010, I suppose either all 32GB sizes were pretty high end or some corners other than it not being the fastest one around must have been cut in the process.
So far no issues though: only one GPS down and one "all telephone functions have been desabled.

And of course the batteries.
