> You're still going to have to carry around a keyboard, mouse, cables, and probably a screen. It's going to be far, far easier to do that with a laptop/surface, or even a tablet, than with their setup.
Um, what? Why would you carry around all that stuff? I clearly described scenarios in which places would already have that setup for you. You just dock and go. Just like today you don't carry a router around with you or anything else.
> A desktop is going to have more power, a laptop is going to have a form factor that's much more convenient to carry around, and more battery.
"More power" doesn't mean anything without context. If you're just writing papers, code, even playing some types of games you likely have plenty of power for this already in your phone. If you want to play FarCry then obviously yes you're not going to do that from a phone.
A phone is more convenient to carry around than a laptop. If someone can supply you a laptop that your phone simply docks with you wouldn't need to carry it around which is precisely my point: the phone (or possibly another, smaller device) could be your personal computing platform and everything else around you simply visualizes the data contained within.
