Microsoft have themselves greatly accelerated the decline with Windows 8, everybody sees a tablet OS and fanboys defend it by saying "tablets are the future, the PC is dead" and so people either buy tablets (iPad's) or don't bother upgrading their PC at all.
The funny thing is Microsoft have abandoned one of their biggest markets in favour of tablets where they're nothing but a bit part player feeding off scraps. Microsoft management need taking out and shooting.
Yeah, Microsoft effectively gave the Desktop PC crowd a two finger salute.
They designed Win 8 to mirror a Tablet and then made it purposely obtuse for a traditional Desktop power user to use.
In their heads this was a good way to ween those Desktop users on to their Tablets instead.
All the so called industry experts agreed:
Oh... that's a brilliant idea....
In reality its hurt Microsoft quite badly, while those same industry experts now say "oh, its nothing to do with Windows 8.. no no no no no...."
It just goes to show how idiotically out of touch these idiots are and how little they know and understand.
Microsoft will now have a 'boot to Desktop' option in Windows 8.1, so perhaps they have now realized that no one likes that Metro thing and no Desktop user is switching to a Windows Tablet.
But i wonder how much they have actually learnt. Will we also see a return of the Start Menu, and all of those backed functions access that they have hidden or taken out completely in Win 8.

As for AMD, Intel and Nvidia.
AMD have an extremely tarnished name, Their CPU's need work on the IPC and efficiency front, but they are well priced and they are not as bad as a lot of people would like you to believe, they are a viable, more cost effective alternative to Intel.
Intel's CPU's are way to expensive, 190 for 3570K and 280 for the 3770K is silly, IMO.
A lot people thinking about going Dsektop Gaming look at that, and after being told consistantley a 100 Pound FX-6300 or 140 Pound FX-8320 is not an option and is a really bad CPU..... Get Intel.... they just think "Stuff that, an xBox 360 costs less than the
only CPU i can have: alone"

i get a real sense that the only reason Intel price they way they do is because of that brand thinking.
if Intel was to drop its prices by anything more than a token amount it would cut very deep into their revenue, they would also have to restructure and down size, just like AMD did. which would send a very bad signal to investors.
For Intel to remain as they are today they need to keep the prices high and sell as many CPU's as they do today, if the market continues to shrink they would have to put the prices up accordingly, whats worrying about that is Intel's prices have been creeping up in the last year.
With GPU's its the same, they just cost to much, especially Nvidias GPU's, again for the same reasons as above.
AMD's future: before restructuring they were twice the size of Nvidia with exactly the same level of revenue (1.2BN)
Before restructuring (Q4 2012) they made a $500M loss, after restructuring (Q1 2013) its down to under $200M with a small revenue decline, but a small margin increase, this is better than they and anyone predicted, that restructuring is also still ongoing.
2013: They have a partner in Vizio who will be using AMD low power APU's in their Tablets and ultra thins, Lenovo and Fijitzu will also use them for some models. (currently they are better than Intel)
Notebook APU's and HD 8000 GPU's are currently shipping to such 3'rd party markers. as are discrete Desktop HD 8000 (re branded HD 7000) GPU's
Desktop APU's should follow some time this year, one or two new HD 7000, one being the long awaited HD 7990.
possible GCN 2.0
real HD 8000 Deseret GPU's, Possibly an FX Piledriver refresh.
There are a couple of significant SeaMicro server contracts signed.
Minimal IP revenue from Nintendo.
Much more significant revenue from MS xBox 720 and Sony PS4 APU's
2014....?
Intel:
2013: New Haswell CPU's which will now doubt be popular.
