Yes, desktops will always be required to create the apps, games, and the like that run on portable devices. Though with society being overtly and covertly dumbed down, both unwillingly, but primarily willingly (through entertainment, propaganda, and other means of distraction), more and more people, especially the young and oldest generations will flock towards portable devices and the desktop will probably become more of an "order on-line" affair as opposed to "drop to nearly any local retail store and pick up a unit" affair.
It will be like the original Wii... there will be great games to be had, but all the local stores will carry will be the made for children and old folks selection instead.
That's my prophetic vision anyhow. As for privacy, yup we'll keep giving up piece by piece by piece, and still we'll remain ignorant of the fact that the threat lies not across shores, or in a cave somewhere, but right in our own back yards, in D.C. in the white house, commerce, the banking structure, and so forth.
Hurray for progress!!!
