I did think it odd that he was talking about the durability of a product that he'd barely unwrapped. But his other points seem cogent, and are orthogonal to how long he's used any of the products.
I don’t think he really talks about the durability, as much as the repairability.
For example, he notes that he hasn’t road tested it yet:
> However! Most of my use of this computer was from my sofa, while I was recovering from hip-replacement surgery. I haven't road-tested it at all.
> But I'll note here that if it turned out that a component failed due to my usual rough handling, I could replace it with a standard part in a matter of minutes, myself, in whatever hotel room I happened to be perching in, using a single screwdriver.
That reads to me as a pretty specific disclaimer and that he hasn’t stressed the durability, but more that he has a plan if it isn’t as durable.
(Though it’s a long article, and maybe he said something about durability that I missed)
