You most likely chant the same thing as in 2008. Consoles kill PC, now its smartphones and tablets. Guess who always lives on and grows..the PC.
No of course not but even if I did, I'd still be on the right track because...only the paranoid survive.
What you are suffering from though is marketing myopia. You assume that PCs equates x86. They do not. Or do you assume PCs equals Windows? Surely you would agree that it does not. PC stands for personal computer. Is a smartphone a personal computer? I think so. Is a tablet? I think so. Is an ARM based chromebook? I think so. They can do almost everything a Wintel PC can do. Not every Windows app works on them but neither do they work on MACs. At the same time there are some great apps that work on these other devices that don't work on Wintel PCs.
The corporate world, I have doubts on as well. I talk to some senior IT types and what they tell me is its all about ubiquity now - accessing data from any device. Makes sense, simplifies their end.
Sure PCs have more horsepower than smartphones and tablets but as PCs are dumbed down, while the ARM vendors continue to innovate, the gap narrows. Combined with the lighter, more innovative OSes vs the bloated Win8...Wintel is ahead but ARM/Android/Apple are catching up (I'll be interested to see how well the acer $199 chromebook does - I think it'll do ok but the battery life and the acer name are sure drawbacks - still I think this is something Intel and AMD (while they're still around) should embrace - its not like Microsoft asked their opinion on their Xbox initiative...
Things always look rosy for everyone during the technology transition periods. I remember floppy drives being 5.25", then 3.5" came along and
at one point PCs had both installed - imagine the growth!!, Teac thought the 5.25" 1.2mb FDD would never go away. It did, as did the 3.5" 1.44mb. The # of humans is finite, the # of hours in a day is finite, if I spend less time with device A, it means I spend more with device B because B does more for me. It also means I'll upgrade A less often and I'll want to spend less on the device, I might ditch A all together.
By the way, I never bought in to the console taking over mainly because the hardware is up to standard only once every x years, the rest of the time its behind. Which is an oxymoron given the application.
Lastly, my anecdotal experience on wintel PC demand right now? Bad except for gaming, mobile or desktop, where the kids are definitely buying. Intel wants ultrabook to get down to $699 or less, maybe they should be working on getting the performance of gaming notebooks up and the prices down (its pathetic that a NV 640M (DDR3, not GDDR5) based notebook sells for $1,000+...
another lastly - guess who is the most innovative PC marketer right now? Google.
Nexus 7, then Nexus 10, then the Samsung $249 Chromebook and finally Nexus 4 all generated a lot of genuine PR, good reviews and sold out status because of the feature set and pricepoint. That's a sad indictment of the "PC" business if you ask me.
