Whatever, but when you use a full sized keyboard and monitor with these small devices, you’re just reproducing the old desktop configuration.
You have portability with your small device, but you aren’t sticking your full sized keyboard and 20” plus monitor in the carrying case with your tablet or smart phone, and you aren’t holding those two full sized components in your hands when you use them with your small device.
The point is, very few are actually abandoning the old desktop configuration and doing all their work on the smaller devices. And all these articles about the death of the desktop are pretty pointless. People are just setting up the desktop computer with different components than the old desktop setup that’s been around since the 1980s.
I’m typing this on my phone. In the future I believe the phone will become a full fledged pc device. You will be able to dock it at work or at home. I do think there will still be a place for the desktop for graphics and other intense computing but most will opt for the more portable device. Desktops won’t go away but their numbers will keep declining.
