>I suspect this behavior will continue as these young people grow up
I don't. I spend a lot of my time browsing on a phone. I could probably be counted in that "cell mostly" demographic. You can't get work done on a phone though. When I actually need to get things done for school/work/etc. I'm using a real computer, not a mobile device.
Mobile devices are rapidly becoming "real computers". I have 4 cellphone sized ARM devices in my house that are capable enough to use as desktops. I have wireless keyboards for them. Several devices supports streaming the display.
For many Android phones, you can already use them as desktop replacements of sorts, with HDMI out (including some with "wireless HDMI") and bluetooth keyboards.
