MisterMegaByte :
More specifically MSI GT and GS series and Asus G and GL series
That is indeed an interesting question. Here's my humble opinion (laptops only):
High-end devices typically survive on higher profit margins, justified by early access to new technology (e.g. 4K displays, latest CPU generation and graphics series). Much like cars, prices plummet the moment you open the box. They do retain some value because they can leverage their 'past glory' when competing with mid-end devices. Even so, a 2-year-old, maxed-out MSI carries only a fraction of its original commercial value because in the course of those 2 years, most of the cutting-edge tech of the MSI will have trickled down to mid-end devices. This is good news for manufacturers of mid-end devices - except for one problem: Games.
As
WyomingKnott indicated, compounding the tech-driven situation is the frenetic speed at which game developers expand the 'recommended settings' for next year's game. This usage-driven trend combines with the tech-driven pace to make it effectively irrelevant to engage in anything to do with quality, as in durability or longeivity; it just doesn't make commercial sense. This is good news for manufacturers of low-end devices, because it creates and perpetuates a market for cheaply made, non-customizable throw-away gadgets that are not designed to last more than 12 months.
And the consumer? Well, if people still think that this industry is consumer-driven, just take a look at the posts on this Forum.
If the 'future' can be defined in 2-year increments, I suppose high-end devices are future-proof. For mid-end devices, that 'future' is closer to 18 months, and 12 months for low-end devices.
