Re: But at the end of a lease, the leasing company owns the equipment, not you
The author was very much talking about buying a phone and a laptop through a payment plan, which admittedly is not leasing in the sense we know it from e.g. cars. Unfortunately this does distract from his chain of arguments (at least it adds confusion). However, since at the end of a lease you are often offered to either buy the product or take up a new leasing contract with a new car/phone/laptop the point still holds:
Yesteryear's product is still good enough and will be for another two or five years - so no need to upgrade and get a new shiny thing.
There is no need to lease a product and then the next upgraded/extended/improved version, ad infinitum, because there is no big improvement over the last iteration. Breaking through the enforced upgrade cycle of the service provider makes sense economically - you paid for the stuff over 24 months or so, or can finally buy the leased product - and environmentally - no additional ressources used in the manufacturing of yet another laptop/phone/whatever, reduced waste.
Interestingly our company was the middleman in one of these games, we did lease the hardware from a provider to distribute it through other contracts to our clients. We were now forced to actually buy the hardware, which came with a ton of fun for finance (CapEx vs. OpEx, up front costs instead of rate payments, etc.). The laptops we provide to our customers (and that we use ourselves) are highly standardised and have not been changed substantially over the last four or five years. Broken machines are often replaced by a machine returned to the department responsible. The hardware is boring but functional and reliable (as far as I can tell). I like boring, the tools must not distract me from getting the interesting stuff done. There are currently talks underway to source the next model, but that might take another year or so before they finally crop up in the "wild".
