Kinda doubt it, with the chips an idle fab is still gonna cost a pretty penny and I think he have reached pretty damned close to the limits on die shrinks, so they'll still crank out enough chips that I doubt prices will climb much beyond what we see now.
But as someone down in the trenches those pundits with their "Death of the PC,grandma is buying tablets" bullshit? hey morons, it was a BUBBLE and like all bubbles it had to burst, what we are seeing now at around 200-400 million units a year is the NORMAL STATE, its only the bubble that is over. this is as stupid as somebody saying "Well you can't flip houses for instant 40% profit anymore,houses must be dying". Its total horseshit.
For those that missed the memo the MHz wars created a bubble, with single core speeds so easy for your even less than average programmer able to take advantage of we went from a pre-bubble lifespan of 5-7 years for a PC to one where a PC would be damned lucky if it lasted even 3 because the chips were advancing so fast a PC that was just 2 years old would struggle to run the latest programs. When we switched to cores because taking advantage of SMP is anything BUT easy, with many programs simply not able to thread, and the number of cores jumping so fast? The programs quickly got blown away by the hardware.
I mean look at what my cheapest build was FIVE years ago...Phenom or Athlon X3 with 4GB of RAM and 500GB HDDs...how many folks will be able to slam that setup enough to need a new one? I have a customer that does extremely intricate Solidworks robot design on a Phenom I X3 and he is happy as a clam with the performance. even myself, who is the major multitasker and rarely have less than 4 things running at once and who built a new PC every year and a half like clockwork, what am I running? A 4 year old Phenom X6 with 8GB of RAM and 3TB of HDD space which no matter how much I throw at it has cycles to spare so other than the GPU upgrade I'll be getting in the fall why would I build a new one? On the mobile side I lucked into one of those AMD E350 netbooks, gets nearly 5 hours on its 3 year old battery and does 1080P over HDMI, why would I buy a bulky new full size?
So despite the "sky is falling ZOMFG!" articles that I'm half convinced is being encouraged by Ballmer trying to burn MSFT to the ground by forcing them to become Apple (like folks are gonna pay $1000+ for walled Windows gardens, not likely fat boy) PCs aren't going anywhere, now that the bubble is burst folks will just be going back to the 5-7 year cycle. if anything not only have I not met a single person that is "getting rid of the PC" (and since I'm supplementing my PC work with home theater I'd have plenty of opportunities) but its the opposite, even the kids have their own PCs, they have PCs up the ying yang...which is of course why they aren't buying as many, because that 6 year old Pentium D or first gen Athlon X2 still surfs the web just fine,runs Win 7 just fine,so why fix what I ain't broke?
