The article fails to fully take into consideration the progression of hardware and technology.
Simply put, CPUs and GPUs are quickly reaching the point that they are outperforming the needs of the average user (including most gamers). You don't need a bleeding edge i7 to work on your spreadsheets or check your emails or to do hardcore gaming nowadays, about the only thing you really want top-of-the-line hardware for these days is for very heavy-duty professional work such as CAD and video editting. You could easily pick up a CPU from several years back and it would still run almost everything you do today fine, which is a testament to how far processing power has grown in comparison to how slowly the needs for such power has grown.
On top of that, PCs in general have always been built to last (besides those $250 friday night specials). Unlike smartphones/tablets which are honestly designed to "go out of style" in a few years, either by way of hardware failure or forced hardware/software obsolescence, PCs can easily last a decade or more depending on how well you take care of it.
Hardware and software that last and remain relevant for a long time mean lower numbers of "replacement/upgrade" purchases, which is part of what's behind the notion of "declining PC sales".
