Re: Mature market.
Yes, the PC market matured, in much the same way as the Video Game market matured during the '80s. Everyone can remember that bloodbath that video game manufacturers took then...only to find themselves sitting pretty in the '90s / '00s.
Let's do a little analysis of the PC market before we declare it dead, shall we? The PC, in all of its form factors, is used for Accounting, Engineering, Graphic Art, Word Processing, Databases, Computer Aided Design, Video Game Design, Programming, Math, Entertainment, and so on. No other device on the market is as versatile as the PC...it can do everything, and it can do it well, provided you do not cheap out on the hardware or software. In essence, it's highly adaptable, perhaps a magnitude or so away from human beings themselves in terms of adaptability (for now)...and that tells us one thing -> before the PC is going to 'die,' all of its less capable, stripped down variants will go first. It's not the omnivores that go first, it's the species that have stringent needs / demands that can only be met under certain conditions. As such....I do not see Smart TVs dying out, nor do I see the web-enabled consoles found in cars these days near extinction either, nor do I see smart phones suddenly being replaced with a pair of tin cans and some string. Verdict? The PC is versatile, adaptable, and unlikely to die any time soon.
So what's really driving all these proclamations of death of the PC? An excellent question, and I do not have the answer. Why are PC sales down? Does everyone who needs one have one? Impossible, most of the undeveloped world has yet to be fully tapped. As for the developed world, the upgrade cycles as well as new people being born ensures that new PCs will be continuously acquired, provided we do not suddenly revert to an agrarian society. What are the likely suspects? Well, let's see here...Windows 8, which manufacturers were banking on, has not exactly wow'ed people into buying new hardware; additionally, the global malaise of a malfunctioning economy is making people focus more and more on cutting costs / corners...as such, the upgrade cycle may be lengthening.
