the pc will only die out when a tablet can super-compute
until then it will just loose some market share to people that like to dream the dream of being independent from the wall socket
as to when, how or why exactly i cant comment, i don't have a crystal ball but i imagine it's quite a few years off yet
even if a pc is considered an old design i'll probably keep using it until something out-specs it
i'm a performance kinda guy i don't really care about mobility because if i'm not at home i'm busy so carrying around a mobile gaming device really isn't viable for me personally
ive been keeping a close eye on the tegra systems, and i think they have promise if they can be scaled up and die shrunk for more power and efficiency
but even then, i don't see how i can fit optical drives, array of usb ports, gaming pads, full keyboards, powered hd sound-cards supporting hd audio devices or phantom powered microphones
( you just try plugging a 600ohm headset into your ipad :S )
also, where do i store my 4 terrabytes of pictures, podcasts and assorted other media?
that's before you do anything outlandish and plug an xbox controller or simulator or flight-stick controls into it
and honestly, none of that is 'portable'
the pc has a place, and it's for enthusiasts who like immersion in games, want to multi-task programs
encode podcasts or home videos, record sound and have beyond hd quality audio and video, rediculus display sizes, and or design with programs, upgrade nearly endlessly with platform designed components so you never go out of date
run the latest games at the most intensive possible settings, with more mods than original content
everyone else is happy with their basic audio, touch screen inputs and apps and that's fine for it's purpose
but they have a long way to go before they can dominate the atx platform on any technical level
and this has been mulled over so many times it's unreal, anyone that starts these arguments isn't looking at the whole picture
yes, you can do ALOT of cool stuff with very little resources, great.
but it isn't replacing the atx platform, also most people have never experienced what a decent pc is capable of to comment on it in the first place, partly because the news is printing crap like this making your average consumer more likely to believe it, which drives pc manufacturers to produce ever cheaper pc's to try and entice customers
back, which in turn makes this whole mess a self-forfilling prophecy..
ever hear of a bank run?
protip:
news corporations have been reporting half truths and complete lies since their conception and have VERY LITTLE actual practical knowledge of the millions of topics they report on
protip2
allot of those mobile devices are being bought by people that also have pc's already, but no mobile device thus
'mobile devices are outselling pc's so they're biting the dust'
is hardly surprising, and a terrible misinterpretation of the data
