This reasoning sounds a little lacking, but it's probably a disconnect from my understanding of "mobile" and "cloud" vs. the commenter's intended meaning. Clearly we need different form factors. We have smart phone size and tablet size. We definitely need workstation size. But I see mobile as a natural part of the evolution to the cloud. If data and apps can live in the cloud, then we're not tied to a machine at a desk. We can carry devices with us. And then when we get to a desk, we can keep doing what we've been doing, just on the larger machine. That's what cloud computing keeps talking about. But mobile computing is a piece in the cloud puzzle. Who cares about keeping data in sync between all your computers if you only have one desktop machine? I only care if I have a machines for each form factor and/or location in which I may want to do work.
Also, one possible technological scenario is that our smartphone acts as our central profile repository and when we get to a desktop machine the smartphone talks to it to connect to data, apps, and log you in. In that way the desktop becomes a seamless part of the mobile experience, providing the larger form factor as needed.
So you can actually implement this as all mobile and no cloud, or all cloud and no mobile, but the two are rather synergistic when combined, since mobile devices talk to the cloud and download software from the cloud. Whether the desktop gets my user data from a phone or the ethernet port doesn't matter, but I suspect it could very well do both, using the phone to handle recognizing it's me and logging me in, then using the internet connection to download my desktop apps and larger data. Dropbox can sync data between devices on the same LAN or the internet as needed, so we can do the same for desktop-phone synchronization too.
