In response to a troll demanding to know who had given up his desktop PC for a smart phone or tablet, one wizard replied,
“First you’ll get a lot of users who never even touched the PC. There are about 1.5 billion PCs in the world and more then 5 billion mobile phones… which are quickly replaced with smartphones. Yet in reality sales of smartphones have just barely overcome sales of PCs – but they are still growing fast.
Next you’ll have all the apps ported to smartphones/tables. This stage is starting already but it’ll be few more years till you’ll be able to actually ditch the PC – and keep all the apps.
And then finally users will start abandoning the PC – because it’s more-or-less useless for most users at this point.”
So, the desktop PC is not dead but it’s standing on the edge of a cliff overlooking irrelevance. So many uses of IT do not require a desktop PC these days that it’s not a question of whether but when they will be replaced.
There isn’t anything in there but the CPU and RAM that really needs any size at all. The PSU can be replaced with a brick a few cm3 in size. Everything on the motherboard can go on the chip and there’s no need for any drive, just a USB connector and a video connector. All the rest is wasted material, space, weight and future garbage. The tiny ARM CPUs that can run on USB power have now reached 2.5gHz and quad core and an entire system will fit in your hand.
So, the last desktop PC should be used only where more local processing power and data storage are needed by the user. Those should be few applications like audio/video production.
