Traditional PC Sales Continue To Slide (zdnet.com)
Sales of traditional PCs continue to decline, although the overall PC market is likely to grow slightly next year. From a report: Traditional PC shipments are forecast to drop by nearly eight percent this year, and another 4.4 percent in 2018, predicts analyst firm Gartner. Which means that, by 2019, 16 million fewer traditional PCs and notebooks will be sold than were shipped this year. However, much of this will be offset by the rise in spending on high-end notebooks like Microsoft's Surface and Apple's MacBook, so that the overall PC market will by 2019 be at pretty much the same level it was last year. Tablets -- defined by Gartner as basic and utility ultramobile devices -- will also decline over the period to 2019.
Yeah, it's sad but true.
Even with gaming systems, unless you're the sort who wants a flashy LED-lit clear-side case that looks like a spaceship, you can build a top-performing system just by buying a mass market machine and selecting the video card you want to put into it.
The enthusiast market is still there, but it's mostly for people who want their computer to look like it belongs on the set of Star Trek. I (sadly?) outgrew that once I was out of my 20s.
