At least ten years ago the demise of the desktop was announced, yet you can still buy them at Best Buy and there is a thriving online industry of build-it-yourself to we'll-build-it-for-you.
Those who announced the death of the desktop ten years ago have now pronounced the death of the desktop operating system and its replacement by the cloud. I haven't heard much lately about "Chrome Books" have you? I have heard a lot about corporate servers being raped of their information by hackers though.
I spend a lot of time thinking about ways to keep my files from others online. For me the cloud is a useful model for idiots actively engaged in delusional romantic relationships with their favorite celebrity. Sure
hackers can get access to my files, so can the
FBI, but I don't have to put my stuff up in the cloud to make it easy for them.
Look at your hard drive sometime. It's like a printout of a portion of your mind. An anal cavity search is at least a thousand times less intrusive. As long as I'm alive the desktop model will survive.
