> Apple devices have the longest usable lifespans out there

Are you serious? This is Apple policy:

> Products are considered vintage when Apple stopped distributing them for sale more than 5 and less than 7 years ago.

> Products are considered obsolete when Apple stopped distributing them for sale more than 7 years ago. Monster-branded Beats products are considered obsolete regardless of when they were purchased.

> Apple discontinues all hardware service for obsolete products, with the sole exception of Mac laptops that are eligible for an additional battery-only repair period. Service providers cannot order parts for obsolete products.

If you suggested, that you cannot use 10 years old PC (and I actually have one Thinkpad that old here), you would be laughed out of the room.

> and best resell value to boot, which is also indicative of their lifespan

That's what some users think; up until they try to do that. Then the reality kicks in.
