Google's icon designers are assuming that people are familiar enough with the cloud = Web equation to make its use uncontroversial. Another step away from cyberspace as place.

But with the iPad, it seems like Apple's model customer is that same stupid stereotype of a technophobic, timid, scatterbrained mother as appears in a billion renditions of "that's too complicated for my mom" (listen to the pundits extol the virtues of the iPad and time how long it takes for them to explain that here, finally, is something that isn't too complicated for their poor old mothers).

The model of interaction with the iPad is to be a "consumer," what William Gibson memorably described as "something the size of a baby hippo, the color of a week-old boiled potato, that lives by itself, in the dark, in a double-wide on the outskirts of Topeka. It's covered with eyes and it sweats constantly. The sweat runs into those eyes and makes them sting. It has no mouth... no genitals, and can only express its mute extremes of murderous rage and infantile desire by changing the channels on a universal remote."

Buying an iPad for your kids isn't a means of jump-starting the realization that the world is yours to take apart and reassemble; it's a way of telling your offspring that even changing the batteries is something you have to leave to the professionals.

Apple's customers can't take their "iContent" with them to competing devices, and Apple developers can't sell on their own terms.

I don't want my universe of apps constrained to the stuff that the Cupertino Politburo decides to allow for its platform. And as a copyright holder and creator, I don't want a single, Wal-Mart-like channel that controls access to my audience and dictates what is and is not acceptable material for me to create.

Rupert Murdoch can rattle his saber all he likes about taking his content out of Google, but I say do it, Rupert. We'll miss your fraction of a fraction of a fraction of a percent of the Web so little that we'll hardly notice it, and we'll have no trouble finding material to fill the void.

the walled gardens that best return shareholder value

The real issue isn't the capabilities of the piece of plastic you unwrap today, but the technical and social infrastructure that accompanies it.

"The current system places too great a burden on individual faculty who would, under the circumstances, appear to have perverse incentives: Pursuing these matters lowers course evaluations, takes their severely limited time away from research for promotion, and unfortunately personalizes the issue when it is not personal at all, but a violation against the university."

In the humanities, professors have found technological tools to check for blatant copying on essays, and have caught so many culprits that the practice of running papers through plagiarism-detection services has become routine at many colleges. But that software is not suited to science-class assignments.

a "studio" model of teaching

The parents paid tuition in cash

The idea that students should be working in a shell is so interesting. It never even occurred to me as a student that I shouldn't work with someone else on my homework. How else do you figure it out? I guess that is peer-to-peer teaching. Copying someone else's work and presenting it as your own is clearly wrong (and, as demonstrated above, doesn't do the student any good), but learning from the resources at hand ought to be encouraged. Afterall, struggling through homework problems in intro physics is how you learn in the first place.
