Quality on hardware has been in decline for the last 5 years at least. There are 3 issues that I encounter every day at work on a global scale:
1) Some hardware producers rush their products and they come buggy (engineering issues), then they have to re-adjust their production chains, they will change a component by a new component, .. etc this happens all the time.
2) There are in any hardware quality issues that companies do not talk about. For memories there has been BIG BIG issues and some memories will get killed over time, it is a defective conception product, I've seen it and customers are not informed about that of course.
3) The global commodity suppliers, they want always more for less money, so the Chinese will cut down on quality, and you get worse products.
This shit has been going on since the recession. Everybody wants to cut down on cost, and consumers get bad products in the end.
