"PC Sales Set to Decline For Years, Analyst Warns" --> that's some powerfull crystal ball! Can Mr Reitzes not put it to better use by predicting all future earthquakes, the exact location of levee breaches from hurricanes, lotterry numbers?
"Decline thanks to win8" --> win8 is clearly not helping things....MS is gambling a lot on portable devices/touchscreens, with a significantly risky knock-on effect in the industry surrounding the standard PC.
Tech always advances (doh!) and thus: hardware will always reduce in size, greater functionality will appear in 'lower end' / smaller sized devices, etc., etc., (another doh?)
There will be a commercially very significant number of folk who think they will be happy with tablet devices / ultrabooks, and that's fine for them....we've no problems with that (though this will reduce permanently (or temporarily?) the global 'regular PC pool'). Of course, as we all know and as many of those who don't and ask questions on forums like this, tablets/ultrabooks/laptops/phones always fall very, very short of delivering the functionality/graphic & CPU horsepower, flexibility, economical upgradeability of a 'proper/real' PC. Little Jimmy is going to be very disappointed when he compares the look and playability of his latest blockbuster game on his jack-mini-i-of-all-tab-phone-trades to his friends regular PC/monitor combo.
I think hardware manufacturers and software developers need to work closer together to advertise and push the advantages of the regular PC model. We need more of the old 'killer' titles. This should be very easy to do for gaming, for example, by making sure that video adverts show the clear distinction between different platforms. With this, developers MUST stop simply porting and instead, properly develop for the PC ---> we've covered this many times before but unfortunately, most developers are still only interested in the easy route....they must be aware that 'grown-up' gamers will turn their backs on them and will very likely re-think who they purchase titles from for their future/current young 'uns.
What about about graphic/video editing, audio recording/editing, etc.?
Just my 2 cents.
