For a tech website-- the posters here seem to have very little vision.
My desktop machine is a box on my desk, plugged into a monitor with the capability of communicating wirelessly to a keyboard and mouse.
At some point computer hardware will be fast enough and storage small enough [or remote] that it stops making sense to build large desktop machines and they'll get smaller.
At some point, a device the size of a phone [probably still with a phone in it] will be as powerful as necessary for 99% of all computer users and then still powerful enough for 90%+ of the tasks of that top 1%.
Those devices will almost certainly be able to connect, wirelessly and seamlessly, to the monitor, keyboard, mouse, internet, power, external storage, etc sitting on your desk [at home, work, the hotel business center, etc]. At that point, sitting at your desk, it is no different than a desktop computer. Except that when you're leaving for work you pick it up and put it in your pocket.
Between docking stations, you'll surely get by with touch and voice interfaces as well-- perfectly fine for the light work you do between desks.
